Guild Wars 2

Here is the deal: having multiple weapons for my character, and constanly swapping them between fights I sometimes loose my offhand weapons in inventory window (when double clicking on 2h while you have 1h and oh, 1h lands in spot prviously taken by 2h and oh is treated as drop and takes 1st free place). To deal with it I bought fractal bag for exotic equipement – but as I want to have all my weapons on the top of window, as soon as bag gets filled with loot, everything gets messy again.

So here is my idea: knowing what is the order of sorting loot in bags (equipement boxes, masterwork/rare/exotic fractal bags, oiled bags and so on) I could put them in right order, so that they get filled in certain order, but my predesigned bag would fill as last (as I dont believe in random exotic drops).
Anyone had similar problem and found solution?

Anyway I think that ability to mark certain things in equipement as favourite (with little star) would be awesome QOL addition. Such items wouldnt appear in merchs/TP windows, and would be always visible among all this trash.
