Never Lose Work: Undo & Redo for Document Editor

What Changed

BrainBox's document editor now supports unlimited undo and redo operations.

How It Works

Undo: Cmd/Ctrl+Z reverts your last change

Redo: Cmd/Ctrl+Shift+Z re-applies undone changes

History: Each editing session maintains its own history

What's Tracked

Every change is tracked:

Text insertions and deletions

Formatting changes

Block movements

Table modifications

Smart Grouping

Related changes are grouped intelligently:

Typing within a few seconds is grouped

Distinct actions (like formatting) are separate

Paste operations are single undo steps

Why It Matters

Mistakes happen. Undo/redo gives you the confidence to experiment knowing you can always go back. It's a fundamental feature that makes editing stress-free.

Technical Details

We use ProseMirror's history plugin with custom configuration for optimal grouping behavior. History is stored in memory and clears when you navigate away.
