Emacs - Buffer List - Drop-Down-Menu

Emacs - Buffer List - Drop-Down-Menu

[Will]

Dear all,

if I press C-Mouse-1 the buffer list appears as a drop-down menu at the 
mouse-pointer. However, the justification seems to be messed up and I 
have problems orienting to find the buffer /folder names.

How can I change the justification of the buffer list so ist flushed 
left (like in Emacs menu -> Buffers)? How can I influence the sorting of 
buffer names in that list?

Thanks in advance,

Will

You might check this:  '(mouse-buffer-menu-mode-mult 1). At least you  
can see that what pops up is mouse-buffer-menu related.

Thanks. Never heard of that option. I wonder why 0 or 1 is not the default
value?

BTW, this helps a lot with the organization, but it doesn't really respond
to the OP question about justification and alignment. I agree that the
alignment is not ideal.

Because it's such an old variable that (almost) every value leads to  
different *documented* behaviour. I think 15 or 20 years ago I found  
1 fine after many tries and then said to myself: that's good enough  
for the remainder of my life. But then I discovered desktop and  
session and now so many buffers are saved between sessions that I  
think I might need to increase or decrease that value of 1 ...

There might be more mouse-buffer-menu stuff and variables.

The alignment comes from the second nested format call in mouse-buffer-
menu-alist. I think the intention is to align the flags and file name,
but it also results in the buffer names being left padded, losing
their left alignment. This looks completely messed up when the menus
use a variable width font, as nothing ends up aligned.

On Windows, the tab character can be used for alignment within the
menu, xmenu.c seems to use spaces to align the key codes though, so it
probably doesn't work cross-platform.

Yes. A variable-width font is what I see on Windows, by default - which is
good, IMO.

I think (so far) that the buffer name should just be flush left, and it
should be followed by a single space before the file name. That is, forget
about trying to align the file names. That is the best solution for a
variable-width font, IMO. Besides, there is no reason to align the file
names: they don't constitute a separate field or whatever here.
