It would be good to have a feature of automatic prioritization, for example, if there are 10 files within a torrent (like pics in an album), you select them all or the ones you want, right click, choose this option and the files are automatically prioritized, first file in the selection being Ultra Hight, second - Very High etc., 9 and next ones are all Ultra Low.
And maybe also, if possible - when the first file downloaded, second becomes Ultra High etc, third - Very High etc.
Anyways, Tixati is the best torrent client ever!
