Current Admin Info

Displays info about the current admin screen and its globals, contextual hooks, etc.

The info appears in new tabs in the »Contextual Help«-panel in the upper right corner of an admin screen.

Currently available info tabs:

Contextual hooks - all hooks that have »context«, the $hook_suffix in their name.
Set Globals: Arrays/Objects are hidden and shown on click (js).
Current screen info: Everything that the $current_screen object contains and isn't private.

^{The contextual hooks tab.}

^{The available and set globals tab. Closed Arrays/Objects}

^{The available and set globals tab. Showing an open Array/Object}

^{The current screen tab.}

based on an idea by @StephenHarris here.
