I was thinking something that might be nice to have, that anet could add to their gem store, would be weapon sheaths.
They would be a container that could hold one weapon set. Just one. You put a weapon set into the sheath container. You could bind them in some fashion, so that any time you decide to switch weapons out of combat, the bound weapon set goes back into the sheath automatically, or comes out of it together.
Kind of like how things like crafting or equipment bags work, but with gear you already have and have bound to. I envision something like while your hero panel is open on the equipment list, or when inventory is open, F1-F4 would have these weapons assigned to it.
For me its a way to make weapons easier to locate rather than digging through your multiple bags of inventory. And maybe save a little space and prevent accidental salvage/sales, etc.
I know, there are other ways to do this already, but to me I think this would combine several functions into one handy one… once its programmed in
