The running applications will always be at the conceptual upper.
The file manager stays at bottom, and act as a dock-like application switcher if not triggered.
There is no Desktop, or it is just another sort method.
This is like using an implemented Dash to replace both Nautilus & the dock.
Apologize for not running an open OS right now, and poor on doing graphics.
It should look like these:
Note that files or apps never stack on our running tasks, at least not in a window way. They only, but immediately, come up when we need to find them.
[Info] - To know what's going on
[Focus] - To get things done
[System] - To find things
This architecture could support more multi devices. On mobile, it even gets rid of a "Home" button and ends the concept of going back home.
