DevMode is awesome, but I wanted to post this as a bit of a heads up.
I'll preface to say yes, you shouldn't be developing live and yes, the docs do include a warning(yet very small and not really explaining why).
But I am assuming alot of you have it turned on right now.
It reveals the craft path, file system paths, plugins installed, field handles and a whole lot of other juicy stuff.
Couldn't we have, or is there a way to have, this wonderful feature only available if logged in and/or admin?
