It will be very cool to add a new feature in KTorrent that I have not found in any plugins for it  (afaik , in all the plugins that are already present into KTorrent Mageia8 version).

a plugin/option to list all trackers from the torrents and Globally ban bad/dead trackers from the loaded torrents trackers list,

now that is possible using the tick box before each tracker name in the tracker tab but that is only for One torrent at a time and you have to do it again and again...

So I think a plugin auto handling the ban of bad/dead trackers for all loaded and new torrents at once will be a very welcome addition to KTorrent ^^)
