"QAG supplies all we need" -> What do we need exactly ?

We can handle it by using some properties or something different with some low 
level tricks :)

Can't we make it in both way ?

Looks fine

+1

Looks fine,

Animate, animate every thing :)

just Kinetic in namespace of Plasma should be fine; Plasma::Kinetic ;)
