SUMMARY I can currently sort mailbox names by clicking on the up/down icon, which is a good feature. However, sorting the sub-folder names at the same time is not very useful. This functionality should be restricted to sorting mailbox names only. Perhaps a right click on the mailbox should allow for sorting of sub-folder names in ascending or descending order. STEPS TO REPRODUCE 1. open up kmail, and click on the ascending/descending icon in the mailbox folder list. 2. Open up your mailbox, and you'll the sub-folders structure has also been reversed. OBSERVED RESULT as above EXPECTED RESULT just the mailbox names should be changed to be ascending/descending.
