• The First 3 ( Changing Key Count Mid-Song/Zoom Chart/Holdend fix)
  ok it seems that this is duplicated in a certain part it is true but listen to me a while ago "Thezoroforce" I made a leather engine extension where this was fixed "Holdend fix and downscoll" another was the "generateEvents" I added the zoom chart I think up to 18x and finally change mania but I already tried this and it doesn't work so it can be improved and put

• The note make a sound or make a effect (Lua)
  This is for custom notes like death notes make a sound when you touch theme is inspirate in Shaggy x Matt

• More Shaders
  Like the name say add more shaders
