Hello Paul Seems like you've been inactive for longer time. Would you like to activate and add yourself to our wiki? It would be really nice. First you have to visit the page, then we'll be able to add you as a developer. That's the link: https://sourceforge.net/apps/mediawiki/jedit/index.php?title=Who_is_who Since we have no dev who could even use the new feature, I think it will be postponed.
