In my opinion, the Frame syncdisk should be reworked. Height adjustments are a worthless change that are annoying at most (see: being tall and not being able to fit through doors yet somehow still able to hide under beds and in cupboards). Maybe with it affecting running speed, but that's a meager benefit.
My proposed solution is that since the concept of the syncdisk revolves around high/low heights, you can rework it as:
HIGH option - Allowing the player to jump higher
LOW option - Allow the player to move faster while crouching and in vents
Other suggestions are also welcome.
