Undo button

[CH] & [@Level] will undo intensity changes to the selected channels. (It's a single-level of undo)

Also, Congo automatically saves the old version of your show as a backup when you do a [Browser] File > Save or [Clr] & [Update]

This gives you 9 milestone backups that you can always reload (or import particular items from) if you've made a bad mistake like deleting the wrong thing.
