Maybe you already saw “Roumen’s presentation”:http://blogs.sun.com/roller/page/roumen?entry=new_netbeans_platform_flash_presentation1 but if you didn’t, I suggest you do it right away.

I’m using NetBeans 5.0 now, and I like very much as well but I never knew it was that easy to use the platform beneath it. Neat! Neat! Neat! ;)
