Discard unsaved changes?

This document has edits that are not in any file.

Note: .grid files not supported on this device. I can export .gridpaper instead.

Enable Turnstile?

From now on this file keeps a timeline of itself: every change you save, when it was made, and what it changed from. You can scroll back to any moment.

The file as it stands right now becomes the starting point. Edits you made before this are not part of the history.

There is no off switch. A file without history is always one export away: Export snapshot to .grid.

Why are these changes being saved?

This file keeps evidence, so every saved change carries a reason.

A grid file is one table. The others are left out, and anything that read from them reads nothing until it reads a table of the site.
