Default Jedix 20 help.

Hi all. I need some advice on the Jedix 20 rom. I had Jedix 16 originally. I dirty flashed to Jedix 20 with no problems. Actually, it seems that alot of things run better. The question I had was, when I installed jedix 20, i had an option of page, app size. I did not change the option because it was what i thought I already had on the jedix 16. Anyway, now my apps and text are smaller. I tried to re-install jedix 20, just so i can change that option, but it wasnt there this time. Any other way I can make my apps and text bigger?
