From Noralisia:

Is there currently a way to set a default Profile for the Rotation Bar so you don't have to manually move it for each toon and if you change it on one it will fix it and move it automatically on all the rest if you move it around or change the order so you don't have to do that over and over on all your toons? I have 11 Maxed all toons and would like to have it in the same spot on my screen for all but when I logged in on each I had to move it for each. Maybe make it so that some of the Regular settings could be made like a default profile so if I move it or make any changes to them it will be updated for all my toons, everything except for rotation profiles. Maybe even with a option to use per character or set as default. Like if I don't want the Mini map button to show, it removes it from all my toons. Thanks!!

It should be possible to add such a functionality using Ace3 library: Ace-DB.
