I have improved the usability of the db4o-netbeans plug-in. It is now available as version 0.2.0.
You may download the new version from here.
In comparison to the version 0.1.0, there are some changes. A document describing the new version and the changes made may downloaded as a pdf from the same location.
I think, it is a good base to improve it by adding more features.
Next steps are focused on improving the editor capabilities, exception handling and preparing the source code to add it to the download section as well.
Check out the new version.
Any feedback or comments how to improve are welcome.
