Please remove the OK button from the paint menu
The recent change which requires the user to click "OK" for their selections to be saved is not intuitive and it does NOT warn you that all your changes will be lost if you do not click "OK".
This is a nuisance to both veteran players such as my self and new players. I spend several minutes trying to figure out why my stupid palettes wouldn't save only to discover that the function of this screen had been changed.
The paint menu has functioned for years where changes were automatically saved. Changing it now after all this time without making it abundantly clear how the new system requires you to click OK is confusing.
Please consider returning the paint menu to the way it previously worked.
