@ kalvanotherwhen: regarding 3 & 5 - have you tried OPTIONS tab? :)

Can you add option to see series from PREVIOUS and NEXT week? Also, I would prefer if it can use option "week starts on Monday", if possible.

Until today, I have used EpGuides.com Watcher, and it has "previous/next" buttons, but overall I think epCheck is better.

At this moment, EpGuides is featured on my blog:

But, it seems that epCheck will be very soon replace it both on my PC and on my blog :)
