Highlights the comments and plugins icons in the collapsed admin sidebar menu when notifications are pending.
In the WordPress admin, when the left sidebar menu is expanded WordPress presents you with a highlighted number within the menu itself indicating the number of pending comments (i.e. comments in moderation) and a separate number for the number of plugins with updates.
However, if you collapse the sidebar menu, then there are no visual indications that either types of updates are available. You can view the count of updated plugins by hovering on the plugins icon, but you must manually do that to learn of updates. No such hovering count exists for the comments icon, so the only ways to find out about pending comments are to visit the dashboard, visit the comments admin page, or expand the menu
This plugin enhances the sidebar menu to display a visual indication that comments are in moderation and/or there are plugin updates available. It does so by using a different colored background for the icon (see the screenshot). Additionally, if you hover over the comments icon, it will indicate the count of pending comments. (The plugins icon already provides a count of updated plugins when you hover over it.) The visual indication is also updated when AJAX-based requests are made (so doing an in-line approval of the last pending comment will cause the comments icon background color to return to its non-highlighted color).
By default, the plugin utilizes WordPress's pending/update count background highlight color, which for WP 2.8/2.9 is #e66f00 and for WP 3.0 is #787875.
