The screen drag lock is a great idea (I don't use it, but I can certainly see why people would), but what I'd like is the opposite - the ability to lock it so I can only drag the screen, not objects/dragons/etc. I like to micromanage my merges and always work in 5's, especially in camp, and all too often I try to drag the screen and accidentally merge 3 of my 5 hard-earned items. If I could look around the screen, zoom in, and then be able to unlock and merge it would be awesome.
