I download today your version 1.0 of this plug-in.
1° I try and I see that in each kind of route
, when I save the route
the name of the route is name_route.gpx.gpx
And in one case, the extention was gpx.gpx.gpx .... !!
2° Trying limited circle, when I export it, the window for saving it is openned twice. And in this case, one of these files is unusable.
See join file (change the extention by distroying".doc" and you have a zip file)
