I've been using Balsamiq Mockups for design work for a while now and think it's great for 'mocking up' a design. It's quick and easy to document the design for either web or desktop applications.

When I get the time I do intend to write a review with more detail and some screenshots.

Google has recently released its latest incarnation of the Google Web Toolkit (GWT), version 1.6.

Key improvements include:

• New project structure for easier deployment to Java server
• Use of Jetty for internal Java server, rather than Tomcat
• Multi-threaded compiler for faster compiling
• New Event handler

I haven't had a chance to try it out yet but I'll report back here once I have some experience with it.

There is a discussions section on the Google site for asking any questions and making observations.
