About tab-line-mode

[Angelo Graziosi]

I have a few questions about tab-line-mode.

1. How to group tabs? 
I want that when I work with a .f90 file the tab line shows all buffers I have 
visited in that mode and that are open. When I switch to an .sh buffer it 
should show all buffers in that mode etc.. BUT How to switch? I do not want a 
M-x COMMAND but the tab line should show a button (similar to the < > arrows) 
that when clicked displays the tab line NOT with buffer but with mode: F90, 
Shell, Latex, C etc..

Maybe all this is already there and I wasn't able to find it..

2. How to increase the size of the font with which buffers are displayed on the 
tab line? 
In my case it is too small (see attachment). How to change the font there? In 
my init.el I have

(set-frame-font "JetBrains Mono-11" nil t)

(setq default-frame-alist
      '(
        [...]
        (font . "JetBrains Mono-11") ; font
        ))

but it does not help.

I have noticed that when I close the tab relative to a buffer, the buffer it is 
not closed: clicking the '+' on the right of the last tab, the buffer  is still 
there and in the 

menu Buffer - List All Buffers

To avoid this I have to 'Close' the buffer via File menu...


All the above permanently in the init.el..

Ciao,
 Angelo.
