nbhexedit is a plugin module for the NetBeans IDE. It adds a basic hexadecimal editor that can be opened from the context menu of all file types.
Nbhexedit is perfect! Thanks.
This works as expected for Java projects, but also installs itself as the default editor for c++ projects, which is terribly annoying and limits its usefulness. Deactivating for now. Hopefully this will be fixed quickly.
