Is there a way for non-admin level users (ie. Editor's & Author's who can publish) to clear the caches, but NOT be able to change W3TC settings?
Maybe the ability to turn caching on and off, but again not touch the settings?
I have clients who I frankly don't want to see the cache settings because they'll undoubtably screw them up, BUT if I make them Editor's they get instantly frustrated that their changes don't show up instantly.
Aside, the "Don't cache pages for logged in users" is checked and doesn't seem to work.
Finally, Studio Press' Genesis theme recently added user level controls for who could see what in there plugin, maybe something similar for W3TC?
