Branching

Non-Destructive Editing

When you undo and make new changes:

• A new branch is created
• The old "future" is discarded
• This is standard behavior

Preserving States

To keep a state:

1. Undo to that state
2. Use Project > Save copy... to create a copy
3. Continue editing in either file

Before Major Changes

Before big changes:

3. Proceed with confidence

History is kept during your session:
