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.

I ask the same. When we have an undo button or key on the Congo???? Cause sometimes we make some mistakes and we don't have anyway to undo that mistake.

Please put an undo key to almost anything on the Congo software like channel layout.
