Additional Features
There are no additional features supported by Simple Access Control. The code is simple, small and well documented, 
so you can use it as a starting point for your own access control plugin.

Simple Access Control

Well thought out -- uses filters to hide selected pages and menu items.

A bit more documentation would be nice though -- it took me a while to find the extra check boxes on the right hand side of the post/page editing form.

Excellent

A very simple plugin that hides specific pages, posts and menu items from users based on their logged in staus.

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.
