I did two jQuery plugins that you can see below:

jQuery Msg Alert

jQuery Dialogr

jQuery Msg Alert is a plugin that i did to create alerts which appears fixed at the bottom right, as with the windows from MSN Messenger.

With this plugin, it's easy to send system messages to your site user.

Check the plugin

jQuery Dialogr is a plugin that I made with the help of Ciro Anunciação. It adds more functions to jQuery UI Dialog. Along all normal functions, there are now more three:

Maximize: maximize the Dialogr to entire visible window area.

Minimize: Stick the Dialogr with position:fixed and disable other functions.

Restore: Returns to size and position of the Dialogr before it was minimized or maximized.

It's really easy to use:

$(#dialog).dialogr();
