Not a question really but is there a "Trello Watercooler" forum to put this?
Anyway, I have this personal colour scheme for my collections and board types, so I decided to add a full colour cover on my Inbox items, corresponding to the category this needs to go in.
So like when I'm on an Orange Category board, the orange items get my attention.
Just trying to make this helpful maybe--at least beats keeping endless mails in my 'real' inbox.
