Intent to de-support: traditional add-ons

I don't think there is too much benefit of sorting folders, but account order would 
really be an important feature - usually the most important accounts are the ones that 
added later (e.g. through decommissioning of mail servers) so  i guess there should be 
a way to put them (or at least one specific, user elected account) to the top. I 
regularly get request for a "auto-collapse tree" feature (maybe something similar to 
the way the folder tree is handled in windows explorer, with not every folder visible 
/ expanded).

Or automatically collapsing recently visited folders that have no unread mails left, I 
am sure there would be ample scope for improvement without writing a sorting routine. 
I actually would re-sorting folders counter-productive and difficult to manage, but 
ideally *accounts *should be able to be re-sorted in the account manager via drag + 
drop) . One of the biggest design problems with the folder tree is the fact that one 
ends up scrolling a lot, and that's exactly the reason why I have stopped using it for 
navigation and switched to QuickFolders entirely.
