Thanks for the feedback!

You're absolutely correct - and the reason I did it that way: easier to accomplish for the first version. I have the intention to take a stab at implementing inline comments, but it's not that simple. For comment to be inline, a line index in the GitHub diff has to be specified. More information about that particular API method: http://developer.github.com/v3/repos/comments/#create-a-comm...

You can delete these kind of comments by clicking "Show lines notes below" checkbox and proceeding from there.
