Link two pins and kml files

Hello,
First, congrats for this plugin.
lot of good thing and definitely very easy to handle.
in fact, I think that it is that good i’m just surprised that few things are not possible.
So maybe I didn’t find the good way.

1 – I’d like to link pins with a viewable connection in map, in order to create trails.
2 – In the same idea I was trying to upload a kml/kmz files, but I found no way to do it.

That’s a great plugin, well done!
