the idea is fairly simple, have an option to lock an item so it cannot be sold or traded period until you unlock it

for instance:
Austere Robe<--you have selected this item and now you have a new option in the upper right where you have your sort options you can select with either your mouse or a controller button to allow you to lock/unlock


once locked the item in question is not selectable while selling in a shop or trading until you unlock the item in question

this would allow you to lock the items you consider important so you could not accidentally sell them, including exclusive or rare/exclusive items which you cannot bazaar

devs please consider this, I for one have accidentally sold items I wanted in the past and think many others have as well, the ability to lock/unlock items would be a great addition to this game, please like if you agree with me
