My suggestion may already have been mentioned somewhere.  But after research of a spell has been done we're given the option to increase knowledge to the next spell level or go to the spellbook.  When we go to the spell book we can't select  a spell to learn, whcih is odd.  Not sure if it's a bug, ut I think would be a handy function while there.
