First of all thanks for getting back to me.
To answer your question, both. For example you have an ability in the editors that increases the Locksmith skill, my character is a Sorceress so of course she has Unlock Charm. I wanted to edit your editor to replace Locksmith with Unlock Charm but I didn't know the skill number. I realize it makes no mechanical difference, but it would make me happier to see the change in my character view.
What I'm really looking for is a way to modify the XP of individual characters rather than the party as a whole. It seriously annoys me that all characters have varying XP amounts. It annoys me even more than the main character has less XP than everyone else. I was hoping there was some kind of function reference where I could find a function that could modify XP but the only thing I've been able to find is award_party_xp. Hell I even tried hex-editing the saved-game file and tried to find the XP values in there, but however they're stored in the file it's not intuitive at all and my attempts have been for naught.
