+1 this could be super helpful for me!!
So... I have a few characters who have AU versions or belong to multiple different stories, and I'd REALLY love to have the ability to, say, move the tab of my character for their RP version to the folder for said RP characters, or move a character who is a main character in one comic but a secondary character in another comic into both folders without having to make a completely new character! Allowing the tabs to still be linked to the main character, but to move the tab and make it visible in a secondary folder!
