Class features, species traits, and feats are all very important which come up often IME. Have you tried the current version (CS 2024 v2) with an actual character? Are you running out of space on some of those boxes?? I found them pretty good for the sample PC I put in the screenshots in this thread.
I could see putting other information such as appearance, personality, backstory, etc. along with equipment, coins (but not magical items, especially attuned) on a 3rd sheet.
With the current revision, the second page is currently almost entirely for spells as it is. Removing Equipment, Valuable, and Coins from the right-side column would free space but I don't know what especially that would be used for.
