A few things about the new extension.

First, a few people reported some bugs, which are now fixed. Updating Post Archiver from the control panel and refreshing the page should fix a lot of problems, including but not limited to some photo posts not showing up on the view mode and unnecessarily long search box on Firefox.

And secondly, for now, Post Archiver does not support archiving from the drafts page due to the way Tumblr works. I’m working on it, and will be providing support for that as soon as possible. I’m sorry about that.
