Why would this be helpful?
The More Paint Functions is good. But there is a bad feature. To sacrifice the Copy, Paste and Delete buttons
How would this work?
I dont know.
Anything else?
Secondly, the more paint functions feature clearly states that it overrides the copy, paste, and delete buttons (hotkeys still work). This is not a bug.
