theme settings

Would it be a good practice to store omega sub-theme settings inside a feature using the features module? From what I can see, all the settings can be stored inside the .info of the subtheme using omega tools. We are building a pretty huge website right now and are looking for the best practices in link with the omega framework.

Any tips and advice on this topic would be much appreciated.

Hi everyone,
Is it possible to clear the cache automatically when someone saves theme settings? I am not so hot at drupal yet, but is there a hook that is fired off when theme settings are saved? Can a function be run then to automatically clear the cache? Thanks!
