Nimble Knees

Left pinky not getting enough of a work-out? Sick of being forced to toggle crouch like you're playing Splinter Cell in 2002? Install Nimble Knees!

Surgeons General's warning:

Nimble Knees may get stuck in unwanted positions. To resolve synchronize button state with crouch state by pressing or releasing crouch as required in a non-movement environment (like the case board) then resuming.
