Idea
I would like to suggest a new tab under Hero/Equipment (or Bank), that would list all the account bound items acquired on all characters, whether in individual inventory or equipped. Allowing players to easily move items; say ascended gear, from character to character, without having to relog. This could also include consumables.
Personal comment
I realise that this is a somewhat small improvement to quality of life, and might prove more difficult to implement in terms of programming, nevertheless, I think it would be an overall improvement.
I apologize if this suggestion have been raised in a previous post, though to my efforts, it would not seem so.
Have a nice day, if you will.
