As we've written previously, last Winter Google introduced the (unlabeled) Apps Launcher in the upper right hand corner of your browser window to access their specialized search databases and your Google Apps.

Today, Google has given us the ability to drag-and-drop the icons for those databases and Apps so that we can rearrange them into an order that more suits our personal priorities for accessing them. The capability is not yet available in all accounts and appears to be rolling out to free Gmail users first – before paid Google Apps customers.

It also appears however, that you are limited to the database/Apps icon set already in the launcher. It does not appear that you can promote services Google has relegated to the "even more form Google" screen (like Google Scholar) to the main screen.
