I'd really like to see SHIFT - R be able to restrain people when they've surrendered. It's just so much easier than scroll wheel.
ALSO, the L WINDOWS key be the action and menu button e.g. Walk up to a vehicle and press LEFT WINDOWS to open a menu that allows you to Unflip, impound, Repair and Pullout if cop ect...
Also, L WINDOWS could be used for the same use on players, so press L WINDOWS to search, give ticket, escort etc (if cop)
I feel like that would make snappier gameplay.
I cant see any downsides compared to me previous suggestions lol.
oh and also hold windows key to gather.
