I would like to have the ability to have a button in Unity windows that causes the window to appear on all workspaces. I know you can accomplish this by accessing the window menu and clicking 'Always on Visible Workspace' but I'd like a button like close, minimize, maximize. I know when I first came to linux this feature existed on most window managers but it seems that it's been slowly disappearing.
Is there a way to bring this back?
P.S. The purpose of this is to have a button in the window titlebar that accomplishes this task. I know this is possible through keyboard shortcuts and the window menu.
