I propose we spend the whole time on making progress on short-term roadmap proposals.
In particular, I think we could easily spend 20 mins talking through @tomsmyth's group navigation UI proposal - Refinements to Repeat Group Navigation - #9 by tomsmyth.
I would also like having a few minutes for a quick post-mortem on Collect form notifications -- what in the process went well, what would we like to change for next time, etc. It's the largest feature we've developed in such a collaborative way so I think there are good things to learn from the experience.
