Let me know if you have any comments/thoughts on it, and I can incorporate them before making a release.
It adds a window to the left side of the AH window, where it will save off any searches it finds.
It will create a new entry for any combination of Name + Rarity + Category
A red bar under the name means a category was set, a green bar means a rarity.
Left-click an entry to resubmit the search
Right-click an entry to remove it
If there are more entries than will fit on screen, then a scroll bar will appear - use the mouse wheel up/down to scroll through the list.
