Better tracking mod idea
 

while i dont make mods myself i can tell u i have searched the downloads for a tracking mod that would let u click the name of the creature u wanna track and get the tracking light trail WITHOUT the tracking window closing.

I doubt you can do that. Just reopen the window after hitting OK.

When you reopen the window, the trail disappears...

I agree it would be nice, but unfortunately there's no way to trigger it without triggering the entire track button Press event, which includes the window closing.

Since tracking is an ability spell, this is just not possible.
