I don't use the mouse.  Whereas window-local tab-bar showing a list
of prev/next-buffers allows using the keyboard to navigate.
For example, when the window-local tab-bar shows such tabs:

[buffer-2] [buffer-1] [current-buffer] [buffer+1] [buffer+2]

Then I know that I can just type `C-2 C-x left' to get to the second
previous buffer, or to get the second next buffer with `C-2 C-x right'.

If there is enough space to put global information.  For example, in Gnus
mode-lines are so long, that have no free space for more information.

Exactly.
