Sorting of messages

Valued Delta-team, developer, user,

My person touched the issue of display sorting of messages already on other topics and thought to give it a single topic.

  1. When one (say new device and old inaccessible) gets the older messages by removing and moving into delta folder again, this messages would be displayed after new received.
    (Possible not build all anew when temporary moved, aside of saved time sorting)

  2. If messages are later delivered also send earlier, same, same. This causes often confusion when sending smaller messages after large.

Why not sorting by time send rather then obviously by file saved on server? Or maybe my person does not see well here.

A further additional mass comes by copy messages and paste them elsewhere. Sorting works out strange (other then displayed) which might be caused by another sorting rule.
