Roster UI

Would it be possible to change the roster UI? The ability to sort characters by star rating, maybe even by colour as well. Say I was looking for a Blue to complete my team, press the blue tab and all my characters with blue powers would show. Currently I have 89 in my roster and it’s a bit of a pain scrolling through trying to find suitable characters. Also, when clicking on a character and then exiting that character takes you back to the top of your roster again which is also a bit of a pain. Any thoughts to this?
