The tt URLs View now automatically selects the first URL that I probably are going to open. In decreasing order, the URL types are:

1. markdown media URLs (images, videos, etc.)
   
2. markdown or plaintext URLs
   
3. subjects
   
4. mentions
   

I might differentiate between mentions of subscribed and unsubscribed feeds in the future. The odds of opening a new feed over an already existing one are higher.
