I have looked through that issue and is why I chose to implement this manual category as a way to mark failures. There's a lot of back and forth disagreements on what should count as a stall/failure for torrents and a variety of opinions and concerns. By having a category applied externally, a user can use whatever method they want to mark those downloads as failed through some rules in their download client or an external automation tool.

My hope is to at least get the ball rolling on a feature of this type as the discussion in that thread seems to have come to an impasse.

Should this be approved, I imagine a similar implementation for qbittorrent/rtorrent/utorrent but I use deluge so the implementation was easier for me to start with.
