I searched around and didn't find this in any of the suggestions so if I missed it don't shoot me just consider it support for the previous person's post if there is one lol.
I think with this addition of the new categories coming up in the Pro Version, and even for the basic this would be useful, that it would be very helpful if we could move multiple items at once. I tried different ways to try to select more than one product to move it, but there seems to be no way to do that.
Many of us will want to restructure our categories once we have more versitle ways with the Pro Version, and already I find myself needing to move a bunch of things from one place to another as I try to get my categories how I want them for now. Some of us will have hundreds or even over a thousand products to manipulate around...
So my suggestion is to be able to select multiple products to move, delete, copy, etc.
It would also be awesome if we could actually move the categories with products intact all in one shot too. In fact this would really be helpful because right now I'm trying to figure out how to add things without the subcategories and still make it easier to move later and I just can see no way without being able to move an entire category into a subcategory slot.
