The Default are the default for MC and they can be overwritten in updates.
MC will use the color profile that was last used next time MC starts
You can change the name by editing the the .xml file for the profile
MC will load all profile in that folder. Maybe you had edited the file and it was mallformened. so it should not read it ?
Malformed H'mm… I just renamed after duplicating my "[Default]" Color Profile to "DarkMode" (put "ColorRules_DarkMode.xml" into the "ColorRules" folder) & it still doesn't get set as the Default, I did that since you said the "[Default]" can get overwritten in updates. So where in the XML Settings is the default Color Profile set ? Perhaps I can change that so "DarkMode" is loaded as Default.
P.S: Oh that's right, when I acciddentally deleted my Color Profile I used Task Manager to kill the MC process hoping the delete would be registered, but it was deleted. Perhaps it got corrupted or something because of that ?
P.P.S: Also there's a "ColorRules.tpl" file in the Config folder, wonder what that does ? Also perhaps there should be a "Set As Default" button in the top in Color Profiles Editor ? And there is only a Close button for me, the Save only updates the individual Rules…
