Forgive me if this already exists (I haven't found it).
I think it would be useful to be able to export all backend settings and be able to back them up, or import to another server.
My developement server is a mirror of my current project. It would be slick if I could import or sync SP options (all eleventy billion of them) so whatever changes I make on the test server can be applied to the live server in one shot. The skinning and custom code I'm working on is very dependant on certain features being disabled or enabled to appear correctly.
Just a thought 🙂
