I have seen the video demos and the IDE rocks, it has all the features a developer would love to see in first version
The IDE has not been released yet. Once the next release candidate LR portal(6.0RC2) is released, then IDE will be rolled out as it will support version 6.0RC2 onwards
In my next post I will detail the features once IDE is available for general use.
I also plan for a post with detailed usage of OOB(out of the box) portlets and their configuration.
