Add follow indicator on account select
When I open the account-view of somebody, I see if the current account follows this user. I don't see what account I currently use to view this. (especially important if I get there via an notification, like "User X follows you" - that also doesn't show what account is meant) It get's worse when I want to follow this account by long press - now I get to select from what account to follow this user - but not if any of my accounts already does this.
Adding a Checkmark (if followed) after each account-name would fix this.
Additionally all views could contain a subtle hint on what account is currently used and/or notifications could contain a subtitle on what account was concerned (maybe only if more than one account is set up)
