In reply to Matthew Harris.

I have often heard this from many others. They need something that's a step up from Editor but not have the God-like capabilities of Administrator.

There's not much in-between space there. The manage_options, edit_theme_options, and maybe a few Tools-screen caps would really be the difference. Once you give access to any user or file-editing caps, they may as well have full access. And, with many plugins overrelying on manage_options instead of using custom caps, I'm not sure how secure this is (not a fault of WP).

I think it's something worth exploring though.
