Subject: GroupFavorited plugin: adds 'Popular' tab to group navigation showing a popular pages... 
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=2ecbae308d0fba0ace43009f0d062301b2a86c81;p=quix0rs-gnu-social.git

GroupFavorited plugin: adds 'Popular' tab to group navigation showing a popular pages subset for just posts in the group. Not necessarily terribly efficient, should be tested and benchmarked on non-trivial sites
