From The Show Off Your Geek Toys Dept...
Release 1.1.0 of the Eclipse XPS plug-in is available.
In this new release you can configure which LEDs should be used to show JUnit results, the brightness, whether the LEDs should pulsate (glow) during the test run and a time-out to turn off the LEDs when the test run has finished. Documentation and context sensitive help has been added as well.
Check out the latest screenshot, recent changes and installation instructions.
