Hey -- this seems really cool, especially for one Jekyll site I manage but want a nontechnical person to be able to update. I found a bug(?) though -- I linked it to a site deployed on S3 and published a test post, and it pushed all the newly built files to s3, but didn't set them to the public-read ACL, so I got AccessDenied errors on refresh until I logged into s3 and manually set them public myself.

Edit: Another piece of feedback -- it's really awesome that it picks up on my custom frontmatter when editing posts, but when I create a new post, none of the custom frontmatter fields are there. Can I enter the frontmatter in the WYSIWYG or is there some other way to add it?
