Those would be decent workarounds. I'm just suggesting that Categories get the (I thought very obvious) ability to let you see everything in them automatically rather than having to run shift-click every item in the Category.
This would be ridiculous in ones like "subjects", "series" or "authors". It would make sense for "news" though.
Maybe this will be clearer: I'm suggesting, essentially, that Categories get a +/- box in front of it that sets all of the fields in the Category at once.
