Development Version update:

I have included a new subplugin called Forum Index, please download from here:

https://wordpress.org/extend/plugins/buddypress-group-forum-extras/download/

(make sure to remove the previous plugin before installing this one due to directory structure changes)

install on my testing site:

http://vwgroups.com/forums/

unfortunately some limitations with placement, behavior with the existing subnav ajax tabs, and css (something is auto adding alt class attribute on the tr element)
