I would like to keep sliding if I hit slide and then jump and come back down, or hit slide and then sorta skip off of something. I think having to either press it again or tap your pack to stop/unstick would be fine. Sticky slide as a setting would increase the possibilities of the already amazing movement we have now by simply allowing players to tell the game to assume they want to keep sliding rather than stop. As it is now, every little bump is a momentum killer. If you go airborne at all you have to press slide again before you touch back down otherwise you stop dead in your tracks. This makes losing momentum unpredictable and unavoidable. However if it's assumed that you want to maintain your slide, even if you didn't mean to keep sliding you can stop on a dime by just pressing it again anyway so I'd take that error over losing the momentum I wanted for sure.
