Feature Request: Export "Measure" information
In my map I get the info of the length of a line by using the tag "Measure" in the popup.

So, I get the info of the length in the popup.

But this information is not part of the export function. When I export to geojson, I get all kind of metadata exported like name, description, own metatags, latitude, longtitude and so on....but not the length of the lines. It woul would be great if this could be included.
