So, you want to work with one type of object from a vendor, or want to organize a recipe for some tasty pasta.
You have all this random crap in your bags, and want to sort it out, without having to move every thing to the right or left individually.
This is where the (insert verb) comes in...
You click on a bag where you want to "pull" everything near to, then you select, Left or Right, and from there, you highlight (or just skip to highlight?) up to what bag you want have it's items pulled from. This way, with highlighting, you won't just move your crap from your toolboxes.
Whatever you needed for your recipe, just put last, pull everything over, and then just shift it to a separate bag if you want.
Special SFX? lol
One con I see, is that you'll have to have a specific bag setup, but that would be it.
Questions, comments, concerns? If you like/hate it, etc, please leave a comment, hehe...
