An add-on for Google Drive that allows TiddlyWiki files stored there to be opened and saved directly

I made an app that lets one edit TiddlyWiki files saved in your Google drive and then saving them back automagically. The page is here https://chrome.google.com/webstore/detail/tiddly-drive/oaphhjhbbabdjnpjpiliepphpmnioolo but I think you need to add it from the Google Drive web interface.
I even added an optional ability to save with ctrl + s hotkeys.
