@SioN no clue tbh, I definitely am not the majority of posts on here though, at most I've done maybe like 25-30% of them.
If it's a timer you made yourself, you can make it so it is 'always on top' via code. If not, and it doesn't have that option, I'd reccomend just using livesplits instead.
Most speedruns are under an hour, depends on what you'd want to run. For any ps5 games you'd play over an hour, I'd ask the specific community for that game for what to do. The youtube vod thing would definitely count though assuming that it works. You can also always try recording with a phone, it works for any console.
Mod updating is always nice. Also would be nice to update the bad run issues. Those have plagued the site since as long as I can remember.
