Simple thing what I miss in netbeans 5.5 editor
In eclipse the editor suggest you not only the types (and provides imports if necessary) but also it also derives and suggests the name from the type in camelcase fashion. Sample: ConfigurationItem eclipse's suggestions: item, configurationItem.
This functionality is very useful and it speed-ups the development. Netbeans provides similar functionality with the same keystrokes (strg+space), but it does not suggest you the names. I think it is not a big deal to enhance the editor to provide such a functionality (perhaps it is already there, but with different key-bindings) - it would be great to see the functionality in Nebeans 6.0 or even 5.5.
