> That pull request has been up for a while, is @DrMarcII handling it? I can take a closer look tomorrow if you like, but I don't have any experience yet with that API.

I looked at it briefly when it was created, and was hoping for some unification between it and the other file APIs (whatever we do for file_system and either html.FileEntry or chrome.FileEntry). But I am far from knowledgeable about these APIs, so please work out between the lot of you what direction to go.
