I understand about the realestate need and the effort/limited time on your part. Adding the new attributes to the attribute cycler on the existing skill list would not consume more screen real estate.
As for time, I understand how busy you are. I just wanted you to know how the alteration of the existing character sheet skill/action tabs would have a huge effect upon game play for the next time you happen to be in that part of the code.
best regards
