Hi !
Another thing that I would love to see in further WM release is a bit of optimization.
Some devices only use 1 CPU core and it take ages for them to generate, where the process could be speeded up by utilizing all available processing power.
Bellow I have listed Single-Threaded devices which generation I have noticed to be particularly slow (I will update that list as I come across some more):
Layout Generator
Blur
Expander
Cheers!
