Tixati is running a number of transfers at private trackers.  After some time, several transfers changed to "failed" status for ordinary reasons -- a new HQ torrent replacing previous one, or an official media release caused the torrent to change to banned status.  (This failed status appears in the Trackers tab of bottom panel.)  However, was expecting to see this change to be clearly visible in the main Tixati Transfers view, either by a change in the private tracker icon in the Name column (perhaps gold --> red?), or a change in the Status column (the "Seeding (x)(y)(z)" value changing to a "No seeds" value).  A visible indication of a Failed status for a transfer would make periodic cleanup of dead private tracker transfers easier to do.

have you tried turning on the tracker status column?

Very good, that should work -- to display that column and sort when needed -- thanks.
