The usual pattern for version history is a takeover. You click "see version history," and whatever you were looking at gets replaced by a different screen — a timeline down one side, a frozen preview where your document used to be, a "restore this version" button that dumps you back where you started once you're done. You weren't editing anymore. You were now in History Mode, and you had to leave it to get back to work.
That's a strange way to treat something as small as "what did this say five minutes ago."
History isn't a place, it's a property
In Aviquill, every block keeps its own timeline automatically — no manual saves, no separate document-wide snapshot to manage. That timeline lives with the block, the same way its color or its position does. Open a block's history and you're not leaving the canvas or entering some other part of the app. You're looking at one more thing that block happens to have.
Because the timeline is per-block instead of per-document, rolling back doesn't ripple outward. Restore an earlier version of one note and nothing else on the canvas even notices — not the block next to it, not the rest of the space, not whatever anyone else is editing at the same time.
A history panel implies you've gone somewhere. A block's history is just something you opened, the same way you'd open anything else.
Why the takeover was never necessary
The full-screen history view exists in most tools because the thing being versioned is the whole document — there's one timeline, shared by everyone, and showing it properly takes over the only canvas there is. Aviquill doesn't have that constraint, because there is no single document-wide state to freeze and browse. Each block already manages its own past the same way it manages its own edits, comments, and chat.
So browsing a past state, previewing it, and restoring it with one click all happen right where the block already lives — no mode to enter, no separate screen to leave. You glance back, you go forward, and the rest of the canvas was never interrupted in the first place.
