I'd like to see boxee make note of the difference between when you watched a show from start to finish (with some slack for stopping earlier than the final end of the file) and just checked something out.
Example... my Feed says I watched Angel. I didn't watch the episode of Angel, I checked it out for less than 5 minutes.
I think many things estimate youve watched something if you watched more than a certain percentage of the item. So maybe if it sees if you watched say 50% of something, it tags it as watched vs checked out (or similar wording). It would also be nice to have this variable be customizable so you could set it to 90% or 45% or similar.
