When digitizing in in the field, we sometimes need to add some comments that may act as reminders to revise the polygon's geometry afterwards in QGIS. (Not all changes are convenient to do on the tablet.) It's very fast to add a bookmark and write the edit-task in the Description-field and use different colors on the bookmarks to sort the revisions into different categories. However, the bookmarks are only available in QField and will not be exported to the cloud and thus not available in QGIS afterwards. In the mean time we use an additinal pointlayer to save revision descriptions.)
