Ideally the manager would have windows and containers. Containers can be nested and can be floating windows, splits and tabs. There is no reason why tabs inside a window should belong to one application.

All that being said, navigation in such a structure would be a mess that would need a lot of learning. Also I’m sure a window manager like this already exists somewhere.

A system wide search within tabs would help more maybe.

Like chrome’s cmd+A but for all tabs everywhere
