In a game where item hunts involve mindless spamming of right-click in your inventory it should not be so easy to accidentally sell one of your hard-won items.
And the vendor only allows you to buy back 12 items when an inventory full of vendor trash is more like 30 items? This is a joke.
Here are two super simple fixes:
1) Let us customize our key bindings so that swap items isn't bound to the same key as identify or sell.
2) Let us 'lock' items onto our character so it asks for confirmation if we try to swap them out
Just lost another amazing item to the vendor by accident, I know it's my fault and such but come on Blizzard, at least help us out a little.
