I don't know if this has been suggested before, but I think it would be very helpful to be able to re-order categories in shops and in your vault. Sort of like with the bookmarks where you can drag them and place them in the order you want them to appear.

I love this idea, I was just thinking that the other day when I was organizing my shop.

also organizing WL categories. it makes me cry every time i want to change the order around.

Agreed! I would definitely welcome the option to rearrange my categories for my Wishlist and in the Shops! The vault I don't use so much but I guess some people will find it useful!^^
