2 - It would be useful if there was an automated option to email an Enketo PDF of a completed submission once it is uploaded.
3 - Bring in more tools for analysis in ODK Central, without needing to export the data.
4 - Enable more customisation options in Enketo.
5 - Allow more options for filtering in submissions. You can currently only filter by submitter.
