additionally while browsing items on the MB you can access the submenu to search for items across your various inventories still.
ALSO, for comparison purposes... when listing items for sale from your retainer, you can access a "compare prices" window already by clicking the toggle in the upper right corner of the window... and while in that window you can access a sales history window as well.
