Lock feature for those using touchscreens

I'm sure this has been suggested before but a "lock Base" button would be nice so that those using touchscreens can scroll around without accidentally moving walls and such.

Thanks.

Welcome to the Forums :D
Well first off everyone uses touch screens :P haha
It happens to me a little bit, where walls start moving. gets a bit annoying, but really its not too big a deal. i don't think theres need for it

i dont think it would improve gameplay that much...

Oh but I believe there is. A "base lock" mode would be a wonderful addition to the game. And fairly simple for supercell to do, I would imagine.
