I think it's a missed opportunity that OS's don't provide a native way to group windows into tabs. I should be able to take any number of windows from any apps and group them together and resize them kinda like a workspace but resizable.
There was stuff in this direction in the past but it looks like it got abandoned and now every app needs to build tabs themselves using their own ui and shortcuts.
@mauve that would put the user in control. They might use that freedom to have a bad "user experience" and we can't have that! In all seriousness, take a look GNOME's push for client-side decorations and against theming.
