So, I didn't post comments while I was going adding more bug reports and pull requests, but I guess I should, because otherwise there's no clear way to tell this was updated.

Last Friday, I finished refactoring the Captioned Image plug-in they wrote during the sprint: https://github.com/alohaeditor/Aloha-Editor/pull/635. This was merged already.

Today, I submitted https://github.com/alohaeditor/Aloha-Editor/pull/642, which allows us to get a notification whenever an attribute of an Aloha Block has changed.

Pull request 635 was merged, but incorrectly. So the ability to center images was removed. Here's a pull request to fix that: https://github.com/alohaeditor/Aloha-Editor/pull/643.

Updated issue summary.

Pretty out-of-date by now, unfortunately. I'm also not sure if this is worth maintaining.

Agreed. This was good for the initial stage, now it's pointless. Let's close this.
