   According to the rev history for VIM, persistent undo arrived in version 7.3, released in 2010. So Chisnall may have used it since 2000, but he didn't have persistent undo for at least two of the books he wrote. And it means it wasn't "maintained for almost 20 years", it's at best 16.

   But it is a nice feature.

   I do that by using version control. I have it hooked to my editor so that "save" is "check in". Now I have persistent, versioned, copies of all my states independent of whatever tools I happen to be using.

      Type A. Type B. Save. Type C. Save. How do you get back to state “A” using git?

      You do not have all your states available.

         Maybe through autosave? If your editor makes a commit every time you're inactive for longer than X seconds that should solve that, which I'm pretty sure is how most editor undo stacks work at some level.

         I just tried it in Nextcloud Notes on Android (FlorisBoard has undo/redo buttons), and it seems to work this way. If I type a bunch of words quickly and hit undo, it removes all of them. If I stop for a couple seconds between each word, it undos them one-by-one.
