The standard Drupal system messages are really intrusive once you start to customize your site via Panels and CSS. For me, the green boxed messages push my pages down and break the presentation. Plus, they just don’t look very… NICE. So here is a great module. Nice Messages leverages the JGrowl JS library make the normal messages appear as in the SS below. There are even options on where the message should appear and how long. VERY NICE!
