That would be useful. I've hit pause to check experience and reputation changes, but if you just solved a quest and are still in a conversation, that doesn't work. Maybe something like the conversation log, but it would only need to keep the last couple dozen values. Also, some spell books can teach you different spells ('sparks' can either give you Lightning or Elemental Hail, IIRC) and there are some bonuses taught as quest rewards; if you don't catch the message right away you have to search through your skill list to see if you can find what is new.
