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.

You can embed page, category, and archive menu in your Wordperss site. You can get documentation and view demos from following site:

If you are annoyed with consumption of large amount of window space by page, category, and archive list, this plugin will be useful.
When the bottom of the menu seems to be out of the window, the menu is “multi-columnized” automatically. Also, when the right side of the menu seems to be out of the window, the horizontal position of the menu is 
automatically adjusted.
You can change font-size, color, spacing in the admin page easily.

Page Category & Archive Menu
