Hide certain windows from "Cycle Windows"

[houghi]

I have programs that are running that I want to exclude from cycling
trough the open programs? I am aware that I could hide them and exlude
them if hidden, but I need to see them and be able to use them.

I am running 4.6.1

Not of very high importance, so if the solution would be to upgrade, I
will just wait till my distro has it.

I would also like to have (more information on) more individual settinngs
of windows as is possible in e.g. WindowMaker.
