Excellent. Just a couple nitpicks (on Linux Chromium): * Hovering over either button on the top right opens a menu. I'm pretty sure only the far right is supposed to. * Needs an option to center the content for wide screens. Have you considered adding support for loading files from the user's Google Drive/Dropbox/etc? It seems like many apps would benefit from this. I've been toying with the idea of writing a JS lib to provide a common interface to all the big ones, kind of like how rclone does for the command line but for frontend apps.
