@mitchoyoshitaka believes that when the server is not reachable, the “Publish/Update” buttons should be greyed out. I think a notification that the post will be submitted later suffices, and greying out the buttons detters the user from clicking, and (part of) what I’m trying to do is to make it ok to push that button even when offline.

We’d both love some more input from more UX-savvy people.
