Well done. A little change that makes the media module so much better. It makes me wanna ask... was it so hard to do this like 3 - 4 years ago ?
Anyway, here's a suggestion which will add a lot to the media module.
Give Military Units and Political Parties the option to create a newspaper themselves. It will give them more 'identity' and a lot of history will be preserved. So much better than having the military commander or party president publish an article from their own newspaper only to have this article lost and forgotten soon after when someone else takes their position.
