About This File
Show a legend of your groups in the Who's Online and Recently Browsing widgets, sorted in the order you specify and linked to the search system. Handy so that people know what those group prefixes and suffixes mean.
FYI: Be sure you are running the latest version on the newer versions (4.3.x) of Invision Community. Also, if you end up with errors in the logs that seem to implicate GNI make sure you have EXIF installed - that's the root cause of the problem and the plugin is just getting caught in the crossfire.
Version 5 is for IPS 4.4.5 and above. Untested on earlier versions. Version 5 addresses changes within the IPS search subsystem that now REQUIRES a query parameter to be passed through. GNI urls now append a "&q= " - and yes, the space after equals sign is intentional and necessary. If you edit the plugin template files, do keep this in mind.
