Separate panes from windows

[H-M-H]

I'd like to display the same pane in multiple tabs. I think a very flexible way to implement this would be to adopt the model vim uses:

Summary:
A buffer is the in-memory text of a file.
A window is a viewport on a buffer.
A tab page is a collection of windows.

A vim buffer corresponds to a zellij pane.

This implies that a pane can be attached to multiple windows, for example in different tabs. The size of the pane is determined by the minimum height and width of all windows referencing the pane. The pane may be smaller than a window referencing it. In this case the pane should probably be centered inside the larger window.
