Hey Clashers!
I just got an idea about "Collect all" button on resources such as Elixir Collectors and Gold Mines and Dark Drills. So, my idea is, to add a button which will collect all gold from gold mines for example. Because its good, when you don't have placed all Mines together... And now, you must search for every gold mine and collect gold from each of them. So, there should be a button near "Collect", and its should be on every different resource (Gold Mines, Elixir Collectors, Dark Drills). Its hard to explain in simple words, so here is the picture:

). See ya ingame
