Thanks for the apology.
(It's a bit rude to demand that someone contribute for free to someone else's 
commercial product.)

Great to hear that you are looking at the desktop again.

Also... don't forget Windows and GTK+ styles.

It does not have to be. I believe there will be an QQC2 Oxygen style soon 
enough.

Regarding performance maybe it's good enough for desktop. But there are other 
reasons why QStyle might not be desirable: dependency on QtWidget and alien 
abstraction.

Writing and polishing styles to pixel perfection is indeed lot of work. And 
QStyle has the advantage hat it already exists. However one can copy-paste the 
code to turn existing styles into QCC2 style. (You will have two style to 
maintain since QtWidgets is still maintained)

The proxy style to QStyle that Marco is developing is a good intermediate 
solution for people wanting to develop cross platform desktop applications, 
while waiting for proper native looking themes on each platform.
