The plus sign next the gem counter for buying more gems is rather obnoxiously located, it protrudes too far out into the the game area and I have lost count of the times I have accidently touched it, mainly while collecting from the mines and collectors.
It should be at the very least immediately below the gem count icon, right up against the side of the screen. No one will miss seeing it and it will stop irritating me every time I mistouch it.
Thanks
