I really wish docker (not specifically but containers frameworks) had support for graphical output. Be really cool to containerise visual apps.

You can do it, I've done it, for the express purpose of GUI apps in containers. You have to mount in a Xwindows socket. There's info out there how to do it.

They can-- I know someone who runs xorg in a container with SPICE output support, but not sure on the specifics.

I suggest that you look up x11docker.
