A functional mockup for an automatized mail client. Tired of adding filters for this new mailing list you've subscribed to? And then having to occasionally cleanup the filters for those lists you unsubscribed? What about adding one for this person you met? And then making sure the filters get run in the correct order so the filters for your contacts don't get entangled with shared mailing lists...

Well, I had enough. This is a functional mockup for a more automatized mail client. It simply collapses information in the sidebar about the emails on your mail-box. You can then right-click an item and set it as "favorite" so it will always be visible.
