Worked (almost) perfectly

Unlike the obsolete default WordPress plugin, this plugin imported all my posts (as far as I can tell) maintaining their current state (published, draft, etc.) and even comments. I’ve only seen one error so far—on one of my posts it quoted part of the post and added it as a comment. No big deal.

I tried to donate to the developers with the donate button but they only accept Euros so my transaction was declined.
