If an item is on the ground, its a spellbook, and you have mxpitems toggled on; can now right click and either take itemname or practice spellname. This should help you identify the spellbook quicker and see if you actually need to pick it up and study.
Thanks to Bit for the suggestion.
I am debating adding this to shops also...If I get enough requests I will...
Enjoy,
