Export tracks to .kml/.kmz with preserving their appearance

Automatic export of tracks to .kmz is amazing. But it lacks of track`s appearance, exported tracks are always in one color, without styling, without outlines and without icons.

My idea is to make exported tracks looking as similar as they can to the tracks stored in Locus.

For example, this tutorial shows how tracks can have a different colour with coloured outlines:

I can see that preserving a speed mode or accuracy mode can be hard: http://stackoverflow.com/questions/82...

Also preserving dotted/dashed style wouldn`t be an easy task.

So at least colours, outlines and icons should be preserved.
