BigBrother
BigBrother is a Google Analytics dashboard widget for MODX Revolution developed by Stephane (lossendae) in 2012. When in May 2015 the authentication broke, I was asked to adopt the addon to make it work again with the new OAuth2 workflow.
It took almost two days of work, but with the release of 1.3.0-rc3 it finally works again. If you rely on Big Brother for your own or client sites and I helped you out big time, please consider making a donation.
