I am currently getting LIFXtend 0.4 ready for release, and I am experiencing some problems with the installer. If feel like giving it a try and would be able to provide some feedback, please write me a mail nate@striking.ch
The biggest new feature will be AmbientLIFX, which will set specific lamps to the color/intensity of your monitor.
About LIFXcl: I already implemented a dim feature, but there seems to be a bug in the firmware of the bulbs. The new release will be delayed until I figure out the issues.
