When navigating on pages widget shows links to child pages. If there are no child pages – widget shows „brother“ pages. 
Link of currently viewed page can be styled through CSS. Widget shows nothing if user is browsing Posts (not Pages). 
Admin can configure:
<ul>
<li>widget title</li>
<li>which pages must be excluded</li>
</ul>
Widget can be localized.

Admin Menu Slide is a simple plugin that adds a feature to hide admin menu and make it slide when hovering on the edge of the screen. Works exactly like WordPress collapse menu – you can toggle the feature on/off by clicking a button, which is at the bottom of admin menu. When enabled, admin pages have full screen width.
