Requested Undo for Swap Colours

[TrickyNicky]

Hi. My name is Thomas.

I would like to see a feature of Undo for the Swap Colors action.
Once you will swap between RGB palette, you cannot quickly undo the change, but have to go into the proper swap option again to undo it manually.

Cheers!

File menu, reopen serves the same purpose as undo, but an undo option might be more obvious.
