Feature request: Lock an item to prevent accidental discard, sell, convert or trade

[Kaze3434]

Please implement this. There's been a few times where I've turned in the gear for another class set and then when I go to use it, yellow triangle telling me that I'm missing gear. At the very minimum "lock this gear set from changes".

what you want already exists. "hide gear sets" and the only thing that will display is stuff not set.
