Feature Request; Separate stashes per character

As a new player to the genre, I've gravitated to SSF as my ideal way to play, but I've encountered difficulties in truly keeping my characters "solo self found" because of the shared stash. I understand that many people like the shared stash and switching items between characters, but for me (and I believe probably a lot of other people) I would much prefer to have each character completely separated from the others.

All I ask is an option to do this. Shouldn't be too much work to add I don't imagine. Right now my problem is I have a trade league character and an SSF one, and I cant make any more characters because theyd get ann unfair advantage out of the stash, unless i just turned off all my affinities and used separate normal tabs but that sounds awful!

Please just add this option! I'm sure many players will rejoice. ALL the best, love the game, this is just my biggest issue as a newcomer.
