Add an undo button

[maelp]

Sometimes you want to try different stuff and simply undo the last command and try another one, it would be great if there was at least an undo button, and preferably an undo stack!

Hmmm -- I could implement this by stacking serializations of the repo over time. I can serialize / deserialize any particular state of any commit tree, so every git command could just push a new state onto the stack. Undo would pop one off the stack and load it...

It wouldn't be "pretty" though, in the sense that there wouldn't be any cute animation to get everything back to where it is. I would most likely just fade out the tree and then fade in the un-done version back.

In terms of the UI, it would probably be a command, not a button. Would you be down to do the CSS for the button? I was thinking that the app might need some kind of button bar at the bottom, just to help people get started (like maybe help, undo, reset, and a few others). Thoughts?

Hello,

a "help, undo, reset" toolbar would be awesome!

I don't have time currently to do the CSS but I might take a look at that this weekend :)

Hey maelp -- I implemented an undo stack / command this morning, but my Internet was down so I couldn't push the changes. Hopefully it's up tonight and I can update the site

I'll open a separate issue for the command bar at the bottom

This is great news

Ok so you can undo in levels, the sandbox, and the level builder now. You can undo all the way back to the original state of the tree (or the last time you hit "reset").

Thanks for the idea!

Thanks for taking the time to implement it :)

Wow! Looks like people are using it a lot actually:

I just added some rough logging to see if people are using the site / actually making progress. I'm going to start the origin project, but your suggestion was great!

Glad to see it is really useful, & nice project :)
