It's insanely annoying that enabling developer mode automatically turns on anonymous authentication. If I wanted that on, I would turn it on myself! I frequently use developer mode to deploy non-breaking schema updates by connecting with a new version of my app.

Moreover, it's just bad form and spaghetti-code to have an option on one panel automatically change options on an entirely different, non-visible panel. LET THE DEVELOPER decide if they want anonymous authentication enabled—I assure you, they know better than you do.
