Torrents that has tracker errors such as "not working" should show up as errored torrents.
If that is impossible maybe it could be possible to sort out torrents with tracker errors in another way.
Right now you have to sort the tracker column and trackers with errors will show no tracker, I don't really thinks that a solution.

I tried adding this functionality - but if you add the feature - it breaks the tracker tier change functionality.
Like now you can click a tracker and left-right you have arrows. Those would break.

So is is what it is.

I wouldn't like to see this implemented as it would make it hard to spot serious problems.

In public torrents, trackers not working is really common and very unimportant. In private torrents it's usually a short lived problem that we can't do anything about.
