Let's clear this up: content is in buffers, panes of content are windows.

There are two ways to switch content in the window according to the
tab-bar click:

1. Update content of the buffer in the selected window.
   In this case, the same buffer gets erased and new content
   inserted into it with the same mode.

2. Switch the buffer in the selected window where the tab-bar
   belongs to the buffer's window.  This has one constraint: all related
   buffers should be in the mode that provides the same tab-bar.

I don't think it's right to call these things "windows".  A "window" in Emacs
is the physical area of the screen in which a buffer is displayed.  So they
are rather a layers buffer, channels buffer and paths buffer.

Another variant is to call them "window-subtrees", i.e. as part of the
window-tree in window configurations.  This makes sense too: a layers
window-subtree, channels window-subtree and paths window-subtree.

This variant supposes there is a way to create a special window that
holds the tab-bar, prepare its window-subtrees and assign them to the
tab-bar's actions.
