I know @insiderish and others did a lot of great work trying to incorporate condition lists into the reference application, and @ddesimone has been keen on including that in the PIH distribution of the refapp. A lot of that is documented here OMRS17 Hackathon Condition list, but there are several tickets remaining to finish this work off that would be great to complete before the next release. This seems like it should be a do-able project in the timeframe.
I’d also be interested in having someone explore how some of the latest innovations (eg. by Mekom solutions, Andela, and others) could be incorporated into the reference application. Specifically these could include the new Cohort Builder and the Initializer module.
