Never Lose Your Work: Version History in Thetapad

The Moment You Wish You Had Version History

We've all been there:

• Deleted a crucial paragraph and realized it two hours later
• Made "improvements" that broke your carefully crafted formatting
• Need that section you rewrote three days ago—the old version was better
• Accidentally saved over the good version with a broken draft
• Spent an hour on changes you now want to completely undo

Without version history, these moments are catastrophic. With it, they're minor inconveniences—a few clicks to recover and continue working.

This guide covers everything you need to know about version history in Thetapad: how it works, how to use it, and strategies for protecting your work without changing how you write.

Understanding How Version History Works

Automatic Continuous Saving

Thetapad saves your work automatically as you type. You never need to remember to save—every keystroke is protected.

Behind the scenes, the system creates versions at intelligent intervals:

Timeline of Today's Work:
├── 4:45 PM - Current state (live)
├── 4:40 PM - 5 minutes ago
├── 4:30 PM - Major paragraph change
├── 4:15 PM - Added new section
├── 3:00 PM - Started today's session
├── Yesterday - End of yesterday's work
├── 3 days ago - Major milestone
└── Last week - Weekly snapshot

The system is intelligent about what to save. Frequent minor edits are consolidated, while significant changes are preserved separately.

Manual Snapshots

For important milestones, create named versions that you can find and return to easily.

How to create a snapshot:

1. Click the History button in the toolbar (clock icon)
2. Click "Create Snapshot"
3. Enter a descriptive name
4. The snapshot is now preserved permanently

Named snapshots serve as bookmarks in your document's history. They never expire and are easy to find when you need them.

Storage Efficiency

Version history doesn't store complete copies of every state. Instead:

Delta compression: Only differences between versions are stored. A one-line change doesn't duplicate your entire document.

Deduplication: Content that appears in multiple versions is stored once and referenced.

Smart consolidation: Old minor versions are merged while preserving important states.

This means months of history takes minimal storage space, and you never hit artificial limits.

Viewing Your Document History

Opening the History Panel

1. Open your project in Thetapad
2. Click the History button (clock icon) in the toolbar
3. The history panel opens, showing all saved versions

The Timeline View

Versions appear in chronological order with:

• Timestamp: When the version was saved
• Preview: Brief indicator of what changed
• Author: Who made the changes (for collaborative projects)
• Type: Automatic save or named snapshot

You can filter the timeline:

• By date range
• By author (in shared projects)
• Named snapshots only
• Changes to specific files (in multi-file projects)

Previewing a Version

Click any version to preview it:

• The document content appears exactly as it was at that time
• Compare side-by-side with current version
• See the compiled PDF output from that version

You can browse the preview without affecting your current document.

Comparing Versions

Understanding what changed between versions is essential for recovery and review.

Side-by-Side Comparison

Select two versions to compare:

1. Click the first version
2. Hold Shift and click the second version
3. The comparison view opens

Changes are highlighted:

• Green: Text that was added
• Red: Text that was removed
• Unchanged: Normal text color

  This sentence remained the same.
- This sentence was removed in the newer version.
+ This sentence was added in the newer version.
  This sentence also stayed the same.

Line-by-Line Detail

For detailed analysis, the comparison shows:

• Exact line numbers where changes occurred
• Character-level differences within lines
• Summary statistics (lines added, removed, modified)

Tracking Specific Changes

When reviewing what happened:

1. Identify the time range of interest
2. Compare versions from before and after
3. See exactly what changed
4. Decide whether to restore, copy specific content, or continue as-is

Recovering Content

Full Version Restoration

To completely return to a previous state:

1. Open History and find the target version
2. Preview it to confirm it's what you want
3. Click "Restore this version"
4. Confirm the restoration

What happens:

• Your current document becomes the restored version
• Your previous current state is saved as a new version
• You can undo the restoration by restoring again

Restoration is always reversible. You never lose access to any state.

Partial Content Recovery

To recover just part of a previous version:

1. Open History and find the version with the content you need
2. Preview the version
3. Select and copy the specific text you want
4. Return to current document
5. Paste the recovered content

This is useful when:

• You want one section from an old version but keep other recent changes
• You're combining content from multiple historical states
• You want to reference old content without fully restoring

Downloading Historical Versions

For external use or archival:

1. Find the version you need
2. Click "Download"
3. Choose format: .tex source or compiled PDF
4. Save to your computer

This is particularly useful for:

• Sharing a specific historical state with collaborators
• Creating external backups
• Comparing versions in external diff tools

Common Recovery Scenarios

"I deleted something important"

Situation: You removed a paragraph (or section, or chapter) and now realize you need it.

Solution:

1. Open History
2. Find a version from before the deletion
3. Preview it and locate the deleted content
4. Copy the specific content
5. Paste into your current document

"Everything is broken and I don't know why"

Situation: Your document won't compile, formatting is ruined, and you can't figure out what went wrong.

Solution:

1. Open History
2. Find the most recent version that was working
3. Restore it completely
4. Your broken state is saved, so you can compare later to understand what went wrong

"My advisor made changes I don't understand"

Situation: A collaborator edited the document, and you want to see exactly what changed.

Solution:

1. Open History
2. Find the version from before their session
3. Compare with the current version
4. Review all changes with full context

"I need the version I submitted last month"

Situation: You need to reference or restore the exact document you submitted previously.

Solution:

1. Open History
2. If you created a named snapshot ("Submitted to Journal"), find it by name
3. If not, find the version from that date
4. Download or restore as needed

"I want to try something experimental"

Situation: You want to try a major change but might want to abandon it.

Solution:

1. Create a named snapshot: "Before experimental changes"
2. Make your experimental changes freely
3. If the experiment fails: restore the snapshot
4. If it succeeds: continue working, the snapshot remains for reference

Best Practices for Version History

Creating Effective Snapshots

When to create named snapshots:

• Before starting major revisions
• After completing significant sections
• Before sharing with collaborators or advisors
• At submission milestones
• When you think "this is in a good state"
• Before trying something risky

Naming conventions that work:

Good names are specific and findable:

"Before restructuring Chapter 3"
"Submitted to Nature - Dec 15 2025"
"After incorporating advisor feedback round 1"
"Pre-submission final check"
"Working version before bibliography overhaul"

Avoid vague names:

"v2"
"backup"
"new version"
"final" (nothing is ever final)
"asdf"

Trust the Automation

Don't constantly create manual snapshots. The automatic system protects you:

• Every session is preserved
• Significant changes are captured
• You can always get back to recent states

Use named snapshots for findability, not for safety.

Combine with Git for Power Users

For maximum protection and flexibility:

Thetapad History provides:

• Automatic, continuous saves
• Fine-grained recovery of recent work
• No manual action required
• Protection against accidental changes

Git provides:

• Structured commits with meaningful messages
• Branch-based parallel development
• Integration with external workflows
• Long-term archival with full history

Many researchers use both: Thetapad History for automatic safety, Git commits for structured milestones.

Version History in Collaborative Projects

Tracking Collaborator Changes

When multiple people edit a document:

• Each version shows who made the changes
• Filter history by author to see one person's contributions
• Compare across editing sessions to understand the document's evolution

Reviewing Before Merging

Before accepting collaborator changes:

1. Find the version from before their session
2. Compare with their current version
3. Review changes in detail
4. Discuss any concerns before continuing

Recovering from Collaborative Mishaps

If a collaborator makes unwanted changes:

1. Open History
2. Find the version before their changes
3. Restore or copy the content you need
4. Communicate with your collaborator about the issue

Technical Details

Retention Policy

Recent versions (last 24 hours): All automatic saves preserved Recent days (past week): One version per significant session Older (past month): Daily consolidated versions Historical: Weekly consolidated versions Named snapshots: Never deleted, never consolidated

This policy balances recovery capability with storage efficiency.

Privacy and Security

Your version history is:

• Stored locally with your document
• Encrypted with your document encryption
• Not shared unless you share the document
• Deleted when you delete the project (after confirmation)

Performance

Version history doesn't slow down your editing:

• Saves happen in the background
• Comparisons are computed on demand
• Storage is incremental
• Old versions don't affect current document performance

Troubleshooting

"I can't find the version I need"

• Expand the date range filter
• Check if you created a named snapshot
• Remember that very old automatic saves may be consolidated
• Use the search feature to find versions with specific content

"The comparison view is confusing"

• Try switching between side-by-side and inline views
• Focus on one section at a time
• Use the navigation to jump between changes

"I restored the wrong version"

• Don't worry—your pre-restore state was saved
• Open History again
• Find the version that was created when you restored
• Restore back to it

Conclusion

Version history transforms how you work with documents:

• Write fearlessly: Make bold changes knowing you can always go back
• Recover gracefully: Deleted content is never truly lost
• Collaborate safely: Review and undo any changes you don't want
• Focus on content: Stop worrying about losing work

The best version control is the kind you don't think about. Thetapad's automatic version history protects your work continuously, so you can focus on what matters: your writing.

Every Thetapad project includes automatic version history. Your work is always protected.
