I think there could be some changes/additions to stuff that would make the page way better.

• Add a version check when uploading runs so you can specify which version you're playing on. I'm not sure if that would make a big difference but that's good to have.
• Make so IL's have difference on Sonic and Ashuro, because level designs change substantially depending on which character you start the stage with, basically making every stage have 2 variations. That could be done with a separation like "Green Gardens Act 1 (Sonic)" and another stage as "Green Gardens Act 2 (Ashuro)", then also make categories being Sonic And Ashuro% or individual character, Sonic%, Ashuro%. The game has extreme routing potential, and if the game ends up being taken far enough, those variations of categories and stages would make a big difference.
• Change category names to something simpler, like "Any%" is just beat the game with character switching allowed, then "Sonic Any%" for Sonic only and "Ashuro Any%" for individual character. Also separate Glitched/Glitchless - both full game runs and IL runs - ;now, I know it takes effort to set rules and define what's a glitch or not (example: stage wrap = glitch but over the level = unglitched) but that's kinda important.

I probably had more ideas before making this but I can't remember right now.. I will edit and add more ideas on the future as I remember or think about new ones.
