I'd like to see profiles added. This is because I customise colours to my liking and would like the same customisation across the board without having to manually do it myself. Being able to create a profile for all of my chars and then copy the customisations over to each profile would make it easy and fast. It's also because on some chars, I have the other options set a bit differently from the rest. I feel adding profiles to the addon would be beneficial and would save time and hassle.
