I wrote a guide some time ago about requests of this kind: https://github.com/geoserver/geoserver/wiki/Successfully-requesting-and-integrating-new-features-and-improvements-in-GeoServer I also recommend reading these two blogs by Nyall Dawson, they are about QGIS but really apply to any open source project: - https://nyalldawson.net/2016/08/how-to-effectively-get-things-changed-in-qgis/ - http://nyalldawson.net/2016/08/how-to-effectively-get-things-changed-in-qgis-a-follow-up/ Cheers Andrea == GeoServer Professional Services from the experts!
