KML Layer Position

Hi,
First of all, thank you for this plugin.:)
I added some adjust in KML.j and I would like you analysis it, please.
First
When I put a Polilyne on the map, for example, at the intersection of my KML layer, the element is over the element. 
Do you think the KML layer always stay below the other elements?

Second
The rotation didn't work properly, I fixed it.
