Projectile force region (toggles), Parkour mode, Platform head (toggles), Copy other player's name to clipboard ability (not sure how that would work but I am sure that I hate having to type out people's glorified names). GL on the tech!
Projectile force region and platform head definitely not, because both force regions and custom vehicles are laggy and annoying. Copying names to clipboard seems somewhat of a gimmick for a general purpose tech, although I or someone else could pretty easily make an interface for it. I will look into a parkour mode.
