from time to time when new mails have arrived I tend to jump from one new  mail in one (sub-)subfolder to the next new mail in a different (sub-)subfolder by pressing the ctrl_+ shortcut key.

Thereby a previously collapsed folder tree is opened and the correct subfolder (containing the unread mail) is selected during reading.

However after reading the mail and jumping to the next subfolder which might be in a different subtree, I would like to have my folder tree in the same state as before jumping in for reading new mails, i.e. previously closed subtrees should collapse, whilst previously expanded trees should remain opened.
