I saw the new RQG character sheet uploaded by Galafrone here. See link just below. It is an very nice four page character sheet with more space for everything. I recommend checking it out.
It also had a small table for easy referencing the Skills Category Modifiers. I borrowed it from Galafrone's character sheet (hope that is ok) and made a small printout for my players. Because almost every season end (between adventures) one of my players goes up or down in a characteristic and need to check all the categories again.
Let's say one player train DEX and goes from 12 to 13. First check the bottom table. You find that it gives an +5% increase for the "Major" row. Then check the upper table column "Major". It shows that skills category modifiers for Agility, Manipulation and Stealth goes up because they DEX is in the "Major" column.
Credit to Galafrone and Silvia. I just found it was a very good and compact table.
