well the drawer would be the same as it is...at least i have no complaints with it, i was really just going for the message view area. i suppose when i get some time, and onto a computer with photoshop i could fix it up.
stoid, what functionality are you missing form mail?
also, this is my quick lame mockup, it is pretty barebones and a poor mockup, its just to see how this window system could be used in mail, if you do like it let apple know as i have done!
this message view saves tons of space for view both the actual message and the amount of messages in your folder
i also like the "today" "yesterday" "last week" that entourage has, and in office 2003 for windows there is a "follow up" folder which is quite useful, i'd love it if mail had these features. and one more feature... it would be nice if it gave you the option to list the amount of messages in each folder.
