I would love it if there was an option to auto remove or permanently disable a tracker of a torrent if it errors x number of times.
Removing faulty trackers from 500 seeds is very tedious and time consuming and this would solve that.

try looking at the various options in settings-transfers-trackers

I guess the best thing Tixati could do is give each tracker a count how often it's been observed as unreachable or last time of successful contact. This is to avoid killing off temporarily unreachable trackers.
