I've noticed a problem, I'm not sure if it's been mentioned, I've done a blanket search for the word rollerblader on some pages, but I'm not aware if it's possible to search the whole thread. Either way, I've noticed that the rollerblader toggle either doesn't work at all or only works once, I'm doing some tests on it at the moment so I'll edit or post again with whether that is once per loading the save file or once per install.
Edit: I was being daft, turns out that due to happy coincidence I'd been testing the "one time use" before I rebound crouch from control to control "toggle", I rebound the original crouch to M and it works perfectly. Brilliant mod. I've noticed a few people rebound keys and didn't get how the shortcuts work, if it isn't there already I recommend putting an all caps warning at the beginning of the keybinds section stating that if you rebind a key, the new shortcut will be the rebound one, or change the bindings list to read, (for example) crouch "non toggle" + semi colon.
Edit 2: Electric Boogaloo: Figured I'd point something out to my fellow Rollerblader afficionado's, if you run (not sprint, it has to be a run) then run in the exact opposite direction, you will begin a teleport, it's just a particle effect, but combined with a well timed sideways sprint it looks very cool.
