Hi, Mikey B! Thanks for the comment and questions. I have actually been working on this. If you (or anyone else reading this) have ideas for playlists, I'll be happy to make them for you. For now, I have added a random button. I know it's not much, but it can be pretty fun and lead you to videos that you might not normally find on your own. Note: if you are using an adblocker, you won't see it. No way around that. Sorry.
I am working on a master list and hopefully a way to track everything that you have seen. That way you should be able to browse all content that you have not watched yet and sort by title/release date/director/runtime/most watched/whatever. I would also like to make an achievement system to keep score of the biggest fans by various metrics, a Tromapedia, and a lot more. I have tons of ideas! I'm also working on all the ideas posted in these forums from all the users. I have read every single one of them. Unfortunately, we are tied to Vimeo and there are lots of technical limitations. We are doing what we can, but it's a slow process. As for what is done and when, that's not up to me. I will definitely make sure that your voice is heard. We understand your frustration, and we are truly doing our best to make it better.
Please note that I do not speak for anyone at Troma, I'm just a mod helping out that has a ton of programming experience and a little spare time.
As for the movies you asked about, that's outside my pay grade. I would bet it is some legal mumbo jumbo that wouldn't be interesting to get into.
