semi locked needs some work

Semi lock as is now completly removes the ability to fully lock the screen at any time. this is bad because those using semi lock to learn unlocked will have just as much of a hard time than just learning to play unlocked, and it makes semi lock realy clunky/confusing to use. I think semi lock is a step in the right direction, but it could be so much better, what we need is a way to lock the cam in any angle we want and have it follow you around. Example, your red side bot lane, cant see anything while under tower and have the cam locked, would be nice to be able to move the cam down, lock it there and have it behave like semi lock does now, but cant unset until i unlock again, so that when i fire skillshots i wont move the cam all the way up again when i go to reposition. I dont think anyone plays unlocked 100% of the time, most switch between locked and unlocked to have vision when they need it and return to their champ while fighting, however anyone who isn`t used to unlocked will have the screen flying all over the place. semi lock is great because the cam follows you in the angle you set it but it still isnt locked there, and if you unlock and relock it brings the cam to the last placed position so if i need my champ in the middle realy quick theres no way to do so. So basicly what i asking for is a new hotkey that lets me lock the screen wherever i want relative to my champ, AND have a hotkey to recenter like space does now. semi lock could accualy be removed because the hotkey would serve its purpose. I think this would appeal to a lot more players than the current semi lock, and would make laning on red side in bot lane way easier and fun. This problem is accualy real bad for me as ive been playing locked for years and dont have the time or patience to learn unlock just so its fair game.
