how many times has it happened that someone (usually a toddler) has your phone and when you get it back they've spent some or all of your gems. i understand that SC doesnt want to implement confirmation boxes upon confirmation boxes, but gems equate to actual currency having the ability to lock your gems away so that you have to CONFIRM before you spend any is IMHO a must have feature!
This would prevent all those mistaken taps where someone spends gems by mistake because of a fat finger tap. spending real money to get gems, and then have it just spent by mistake on something you didnt really want is NOT good.
