Item/Equipment lock feature?

Item locking is a feature most mmo games have, for example WOW; where you can lock in a piece of equipment or item to prevent accidental actions like selling or discarding it. It also helps with highlighting items that are important and keeps track of them, these are the main reasons why I wished for this feature, as I would struggle every time cleaning my inventory going through all my items to know which item I need or not; instead of knowing items I locked are the only ones I need would save up a lot of work. I know it might sounds lazy, but I prefer seeing my favorite equipment or item in a safe place.:)
