Just tried LXQT 0.10 with Kwin and it's awesome. The lightness of LXQT and the eye candy of KDE in a balanced way.

Many thanks to all involved. I have a question though, does anyone know whether qtcurve can be compiled ? 

I have seen a couple of tries but the source of the files is dead now: http://kde-look.org/content/show.php?content=40492

Basically I am looking for ways to use the Breeze theme with LXQT...
