One feature I would like to see would be the ability to lock down items in the bank or a backpack so they could not be sold or used in crafting by accident. Yes, I deconstructed some items by mistake that I had put in the bank for another character to use. It was totally my fault for not paying attention, but the second I did it I knew the horrible mistake I had just made.... twice... in the span of an hour. However, a feature to lock these items down would prevent such a blunder, also a player could lock items in their backpacks from being sold to a vendor making it easier to carry multiple sets of armor/weapons in their packs without the worry of accidentally selling or deconstructing them on those sleepy nights before bed... or if you're just an absent minded idiot like I was. Something easy to do lock/unlock in the drop-down menu much like the "mark as junk" and "remove item" choices are now. When you're at the vendor screen or deconstructing at a crafting table, those locked items just do not show up... or show up Locked.

What are your thoughts on this?

sounds nice

i didnt break down anything by mistake, but it was close a few times

this is a real concern.

item in bank should, at least be clearly marked "in bank".

this is something an addon can do however. (still after the api nerf)

Agreed. If items show up to be deconstructed from the bank, they should be able to be locked so you can't do it by accident. I wouldn't mind being able to lock them in my bag either. I did that all the time back when I still played LOTRO.

I think they are now maked as "bank" or "bag" via a small icon that looks like a chest or sack respectively.

Whether or not this shows up when deconstructing I don't remember (I imagine it would, but maybe not)

Either way, there should be a locking system!

Almost word by word the same first couple of paragraphs I asked for a couple of weeks ago, similar to Tera's banking/bag options would do.
