Marks

[shift-reality]

This idea can improve usability: -every mail should have marks which can be added/removed (like post tags); For example: friend,bill,works,later,order ... etc; Of-course this can be done use folders, but ONE message= only ONE folder (parent) otherwise difference is: ONE message can have MANY marks; Left panel (folders view) can display all known marks separated by comma's. When clicks - only mail with this mark are displayed; ; ; ;
