@YusukeUramesh - i only have used utorrent and qbittorrent so far, qbittorrent has a lot of features i don't want to miss anymore, but still using utorrent (2.2.1) as second client, as some torrents can't be cross-seeded on some trackers without using a different client (torrent is already in the list) i just wonder its working without problems for 7-8 other trackers while not for a few others ...
