A particular annoyance I have is that when I am trying to click all the resources/level ups, I dislike greatly when I am both dragged away from where am because of a 'happy moment' (six) or because I accidentally click a person. So my idea is to keep both things from happening when a user is zoomed all the way out. Already most animations are disabled, but I think we could go a step further to make the game smoother for those with very large vaults.
