Rated 5 out of 5 stars

Excellent! Proposal: it would be nice, if deleted messages or messages that are placed in certain folders, where removed from the tree structure. And the possibility to delete a structure with all the mails attached to it or just certain emails, you don't really need in it and then without leaving the structure. So your focus will go onto the previous or next message in this structure. Just a thought!
