Request: Switch for collapsed / expanded email-tree

Request: Switch for collapsed / expanded email-tree

This is a request:

As a unchangable default the email-tree is always expanded. This annoys me as I have a very large tree and have to scroll alot to see if I have received mails.

What I would find to be a nice feature is a switch in the settings to have the tree start in either expanded or collapsed view. When collapsed the outer folders should always show the number of unread mails in the underlying subfolders.
