The community is awesome to provide feedback about quality and features. The comments left to the previous entry, made me improve the NetBeans Module Startup Settings I am developing.

Improvements:
1) a drop-down with presets of jvm parameters
2) library of jvm options with a short description for each one
3) links to performance related websites

Flash started to be popular as a way to explain something which normally takes many words to write it. Then, I created two flash demos, related to the following subjects:

1) Show how to add custom swing widgets to the palette manager (3,6 MB)
2) How to use GridbagLayout and Freedesign (aka: Matisse) each one with different JPanels, but inside one JPanel (or JFrame). (2,6 MB)
