In Field Maps, the Markup feature allows users to capture basic notes on the map without having to "colelct data". Markup can also be shared, but only by either the "screenshot" method, or as a ".markup" JSON file. These files can in turn only be opened in ArcGIS Online or ArcGIS Pro (and then converted into other formats).
IDEA: Add in the option to share markup as a .kml file so that the data can be easily share with other people using non-esri apps and software (e.g. Avenza).
Use case: This functionality would make the newly added geopdf functionality even more useful. It would mean that a user (e.g. a first responder at an emergency) whoc has downloaded a geoPDF to their device from a 3rd party agency, opened it and captured information via the markup capability could then export that infomation and send it to other users who are not Field Map or ArcGIS users (e.g. Avenza/QGIS users) without needing to organise for it to be converted by someone in their org first. This is a time-critical workflow that currently is best served by using the screenshot function (definitely not ideal).
