it would be cool if there was a builtin way to display a notice store-wide. similar to how demo mode works but that could be any text, say smaller shop owner is going out of state for a week. a notice that orders will be delayed would be helpful.
it'd also be cool if there was a way disable ordering (maybe with notice too).
No order disabling (submit to ideas.woothemes.com) but we have custom notices in 2.0
