klonk VS WBO

While surfing the web I came across this blog post: Resolving the Great Undo-Redo Quandary.

Resolving the Great Undo-Redo Quandary\ (31 comments)

My goofy lil' homemade editor does it this way: If you go back in the past and change it, the future becomes the past. This might sound confusing, but effectively it means that the undo stack contains the actual history of "what happened". This means you can hop to any past or future state linearly with undo & redo alone. I just find this easier than navigating tree GUIs and things that aren't worth the trouble to me. It can still lead to a bit of mental gymnastics in extreme cases.

Note that in theory this can cause an exponential growth of the undo/redo stacks because it makes an upside-down copy of the future when you change the past; but in practice it's never been an issue.

I was thinking of adding a feature to navigate back to "last change-the-past", which wouldn't be hard.

It at least makes more sense than most science fiction time-travel plots...

As a maintainer of an open source JavaScript infinite canvas application [1], I was very interested, and now I am a little disappointed. The set of supported objects on the canvas is quite minimal.

Could a self-hosted whiteboard work? * Excalidraw allows images to be inserted * WBO has a built-in grid mode (but no ruler)

You can share and use a Scrumblr only with the link. But no possibility to import other than opening the same board again (and exporting, printing the page as PDF). Same with the whiteboard WBO, but much more complete and polished one (and has SSL).

Aside from kanban boards, a virtual whiteboard might also work well: * Excalidraw (live) * WBO (live)

A whiteboard thing? Like WBO or Spacedeck

Fluffyboard and WBO - I prefer Fluffyboard because it has an Android app.

This one seems to work well: https://wbo.ophir.dev/
