I have a really simple question... is there no undo or redo button?

Hey @salmon-country-61109, there is not a button at the moment, but you can click

Ctrl

+

Z

to undo the last alteration.

@early-train-33247 I would love an undo / redo button. Visibly in the editor to the left of zoom actions. Also with keybinds. A suggested fail safe could be 5 alterations using keybinds and 10 if you visually click on the undo/redo on the UI. Would save me a lot of trouble.
