Grant us the ability to create separate tabs and move our characters into them for organization purposes. Let us name these tabs whatever the heck we want and customize whether they show on the side or in the active selection list itself and with the option to even hide them, etc.
We can use this to separate classes, factions, professions or organize literally anything else.
Also, while this next idea is way less important than the above as it’s only aesthetic, we have been long over due in having the ability to save presets for our character appearances in the barber shop so we can easily switch from one look to another as we wish. Just throwing this one out here because it’s been an idea bugging me every time I visit the barber shop.
