Pretty sure this has been suggested already, but I couldn't find the link.
I know many of us have done this in the past - you go to cancel something from the queue in the provision house or your barracks, and you accidentally hit the "complete order with gems" one instead.
Now, for those with many gems, this is nothing more than an annoyance; but for people who prefer not to pay for the game, gems lost in this manner will obviously set them back if they are saving their weekly gems for licences/scouts/geos etc.
May I suggest the gem icon be moved to the left hand side (or any better suggestions welcome)?
