I was thinking about this, and yet can't figure out how to get it to work. I play a bard, and a big part is twisting instruments and what not. I have my hotbuttons set up with the top left my primary weapon, top right my secondary weapon, and then right below my primary is my bag with all my instruments and stuff in it (bag located in 8th bag slot). What I wonder is now would it be possible to move those three to just above the hot buttons so I could free those 3 slots up? If anyone has any ideas how to do this please let me know, I am trying to teach myself XML as we speak!
