I'd recommend the author use the OAuth 2.0 scope https://www.googleapis.com/auth/drive.file ("View and manage Google Drive files and folders that you have opened or created with this app") instead of https://www.googleapis.com/auth/drive ("See, edit, create, and delete all of your Google Drive files"), if/when they get a chance to work on this.

Anyway, this is really cool and totally fills a niche for me (90% of the time I want to edit org files in Emacs on my computer, but sometimes I need remote access). So I'm really happy to see this exists.
