1) would be very nice to have option `pressing enter in queue changes to source directory` or at least make `enter` to act like double click there, also `space` can mark or unmark selected dir in queue (for marked list I mean)
2) hardly need confirmation on re-sorting queue items.. if I click accidentally on a big queue column header, i'll need 5 minutes to resort it back to original state!
and since `scroll up` button located very close to the column header, such unexpected re-sorting happens from time to time...
