I have started using the GlobalPlugin to integrate jEdit with GNU Global and am very impressed with its capabilities. What I would like to see in GlobalPlugin would be integration with gtags, so that the cross-reference database could be generated and updated from jEdit, and integration with the ProjectViewer plugin so that the list of files to be cross-referenced could be obtained from the project:

• Provide a way to run gtags on the entire project from jEdit. gtags should use the GTAGSDBPATH environment variable (if set) as the location of the cross-reference files.
• Update the cross-reference database when a buffer is saved (use incremental the update feature of gtags and global).
