Wishlist: groups for "program listings" similiar to "graphics groups"

[Helge Hafting]

When writing a text about programming, there are tons of program code 
examples. And they usually have similiar settings. I.e. all are the same 
programming language and the same dialect with the same font options.

After applying lots of such settings over and over, a grouping would
be useful, in the same manner as for graphics. When several listings 
belong to the same group, changing settings for one changes the settings 
for all in that group. And new code snippets just need to be added to 
the correct group, so the user won't have to re-apply several settings 
each time.

These "listing groups" should ideally work both for code snippets in the 
document, as well as code included from external files. In lyx 1.6 they 
don't have the same settings dialog, which is is unfortunate. (For code 
from a file, I need to type "language=C", for code inside the document, 
I can select "C" from a pulldown menu.)


I understand that this might be some work. It'd be nice if the lyx 2.0 
file format includes this change - even if it doesn't get implemented in 
the user interface. That way, the user interface can come when someone 
finds the time, because the file format is in place. (Just a group 
setting for internal and external code listings.)
