My one suggestion would be an All Vault Codes category. You would have to log out of your account to reset your stats back to 0 then unlock every vault icon as fast as possible (including the regular Vault, Vault of Secrets, and Chamber of Time). It feels like a really speedrunnable category because there's routing, planning, and a little more than just menuing to save time. My only concern with the category is that you would have to log out and lose your data before starting the run. Of course, you could always save your data before logging out so you can get it back when you're done.

Gotta love how because there were two asterisks for multiplication symbols it hid them and put everything in between them in italics :p

I decided to do some math to see how long an All Map Packs speedrun would take optimally. • 65 map packs • 3 levels per map pack × 65 map packs = 195 levels Let's assume each level takes about 90 seconds, or the length of a normal RobTop level (a lot of these levels use a RobTop level song and are the same length as the song). • 195 levels × 90 seconds = 17,550 seconds • 17,550 seconds / 3,600 seconds per minute = 4.875 hours (4:52:30) At best, an All Map Packs speedrun would still take about 5 hours. If each level took 10 minutes on average, you're looking at a 32+ hour speedrun. Good luck if you want to try it :^)
