Does the video aspect of iTunes strike you as kind of hacked in and not well planned? The UI refers to videos as "songs" and "podcasts" in various places; is the latter intentional? I have a tough time resizing the video window. Sometimes I right click the video and see a "full screen" option, and sometimes I don't. It's the same video a couple seconds later. I hit command-F and nothing happens; it's still mapped to the visualizer. I don't care about the visualizer when I'm watching video.
The thing that bothers me the most is the lack of episode numbers. Unlike songs, I care about watching a season in order, but in many of the views, it's difficult to order shows or even to tell whether they're in the correct order or not. Am I missing something?
Update: Sam pointed out in the comments that I can go to the "Edit" menu, click "View Options", and make the episode number visible. Duh. I've been looking under the application preferences the entire time. Thanks, Sam.
