Ability to see the shopping list for all characters without being at the AH. (Show me that window that pops up at the AH, but any time I ask, not just at the AH.)

I want to see the whole list when I'm grinding on another character, so I know who to send the mats to, and how much the other toon needs.

For example, I have 100 Rugged Leather, 50 Thick Leather, etc. on the reagent list for my Leatherworker. However, I have another higher-level toon that is a Skinner, and I often have that toon do the mat-grinding for the Leatherworker, since it's much faster to kill more things. I want to be able to click a button to view the whole darn list, so I know when I'm out skinning, that the LW needs 100 Rugged Leather, 50 Thick Leather, etc., and that I also know who could use all that Runecloth I just picked up at the same time. Right now I've just been making sure to visit the AH before going on a mat-run, and listing the things I plan to grind for on a slip of paper, but like in my example, if I end up with a few stacks of Runecloth too, I have no idea who would need that unless I visit the AH again to see the shopping list.

I hope that makes sense! I have a lot of alts, and keep very full queues on all of them for things that could level their skill, or sell well on the AH, etc. so this may or may not be a popular request, but it would sure help me out a ton!
