My suggestion is to introduce a little feature that would allow to categorize Private Trackers.

Better than categories it would be reasonable to have a status of "Private torrents", that way it doesn't remove the torrents from personalized categories.
Or better yet you could also create a status with a tracker's URL: "Private Torrents of:UrlTracker".


Exactly like the Seeding status, you would have statuses oriented to trackers like:


A status = "Public Torrents"
A status = "Private Torrents"  
Multiple statuses that can be created to infinity = "Private torrents of:[ http://[b]First[/b]DomainPrivatetrackerInsertedByUser.com/... ]";  [ http://[b]Second[/b]DomainPrivatetrackerInsertedByUser.com/... ]"  ...

If you use URLs to define a possible status it would be extremely useful for managing torrents from a tracker-oriented point-of-view.


Why doing all that extra work?
You could be thinking about the "big-whales" that constantly donate: they appreciate the depth and technicality of your program.

Who would benefit from it?
There are hundreds of private trackers of people that would appreciate Tixati, hardware is becoming cheaper and people's archives are increasingly bigger,
you will become very popular sooner or later and you do want the popularity to be oriented to people that actually appreciate the depth of your work.


I hope my suggestion was useful to you and I apologize if it was unreasonable: I am not a programmer.
If possible, I seriously hope you will introduce both the generic statuses "Private trackers", "public trackers" and the possibility to create a status with the URL of a tracker.

I am thankful Tixati exists.
