It's probably been discussed before, but one thing that I liked about Destiny was the ability to lock an item, so you didn't accidently trash it.
The thing is, that items in the bank show up during deconstruct, which is kinda annoying at times. Especially if you just bought a nirnhoned weapon (for research) and accidently trash it when emptying out 100+ trash items. A simple option that would lock it or at least toggle if it was visible during decontruct would be fantastic.
