We were recently discussing in the discord that certain categories like difficulty etc wouldn't be added until more people were a part of the community and showed interest in doing those particular runs. So that's just going to potentially show up as time goes on.

As for timing, I believe someone is working on an automatic splitter, but to ask that we start and stop the timer during each cutscene or load screen is pretty taxing having to do it manually, and even more so for anyone who is validating the runs. I could be wrong, but it doesn't seem like it would even save that much time.
