role capabilities

Hi there, I’ve built a website for a customer of mine using enfold and it’s the bees knees, I’ve given the person access to the bits they need and I’m using a role editor to try and prevent future accidents. I’d like the person to be able to modify the theme options by themselves, general styling, header, sidebar options etc. but as far as I can tell those options are controlled by the manage_options capability which also opens up the settings menu, and a potential can of worms. I’ve hidden the settings using a combination of things, but the section is still accessible using the URL. Unlikely to be found but you never know, do I have any options for giving styling permissions to a role, without giving settings permissions?

Many thanks
Matt
