Enhance "Export data" feature to filter to currently visible map

Idea created by vitaly.livshits on Sep 29, 2017

    The "Export data" feature is currently showing data for the entire map. Is it possible to add an option to limit the dataset to just the part of the map that's currently visible? The unfiltered dataset is useful as well, so this feature request is in addition to the current behavior rather than as its replacement.
