Hi, and what's wrong with writing a fix for admin to make "inverted"
m2m relation to show m2m if specified in list_display list? I know
it's not easy to do for one who is not django creator, but since it's
open source... ;)
Core devs, what's your opinion?
Such change is pretty logical, short and non-intrusive.
