Allow account switching.
I have a personal account and an account to stream with my trivia company. I would like to be able to switch between them without logging out. More importantly, I'd like them each to have their own themes--currently if I log out of one and into the other, it still uses the custom theme I built for the other account. Any changes I make with persist if I switch accounts again. Bind layouts saves to accounts locally / store them in the cloud but also allow users to share their layouts (or access any layout saved locally).
