Just finished my first plugin for wordpress called WP Admin Switcher. You can download this plugin here
After you have installed this plugin you will be able to add information of multiple blogs you manage, the plugin will show you a drop down on top of all pages and let you switch between blogs. When you switch the plugin will attempt to show the same page of the other blogs administration panel.
The plugin requires CURL to be installed with PHP. Also please make sure to set the permission of the folder “tempfiles” to 777. Another point to keep in mind is that when you enter the URL of the administration panel in the WP Admin Switcher management page , please make sure you enter the correct URL. Some blogs are set to force www , so the page will keep redirecting to http://abc.com/wp-admin/ if you enter the URL like this http://www.abc.com/wp-admin/ . So make sure that enter the correct wp-admin URL.
Have Fun!
