It's a lot of scrolling down (skip over a lot of things I very rarely use) to access 'Local folders' archive when you have many email accounts. And then scroll up again to take the next email. I love the Inbox section in Unified Folders. But NOT the long, long list below.
Maybe create two sections: 'Inboxes' and 'Other folders'?
Also this 'frontpage' (?) for each account - isn't the information/functions covered in the menus? To me it just seems like a waste of space, and creates clutter.
Thanks for the great job you are doing!!!
