NetBeans IDE as a pure Java Swing app, can use any JVM parameters, it can be specified at netbeans.conf file, as Charlie Hunt blogged about that, see NetBeans IDE: Adding/Changing JVM command line args. Then as Charlie asked to contribute a plugin to configure NetBeans startup settings, I decided to try it, an developed the plugin, see a small screenshot below (click to enlarge).

It's almost done, probably in next few days I will post the NBM (NetBeans module install package).

Do yout think the UI is good, needs some improvement ? I am not very good on UI things, so please, drop a message.

Some improvements I plan to do:
1. optimized parameters will suggest some -X and others JVM parameters
2. restore orginal settings
3. any other you want to see ? drop a message.
