hide/remove modules not needed

Hi,

excellent package and work!. Was looking for an accounting system that was easy to install and get going, that i could interface to my system for posting transactions.

My system is a medical practice management system and will  be posting billings from the my system over to FA. Obviously, they won't be needing mfg/inventory/dimensions. Is there a simple way to unhook these from the menu system.

Thanks,
Johnny
