I want my email organised by sender, not by message. I want a list of senders with unread messages when I open the client. I may want some way to indicate which senders are more important so that they are displayed more prominently in some way.

Maybe this has been tried and it's shit. I dunno, but I like the sound of it. I think it might be a good way to cut through the noise of the inbox. When I get snail mail I will quickly sort by sender (then read the tedious shite first :-) ).

I should try and write it for myself.
