goofy - Desktop client for Facebook Messenger

Javascript

Goofy is a macOS client for Facebook Messenger. But unlike most other clients, it does not use any of Facebook's APIs, but is basically a single-site browser that injects a little CSS and JS into messenger.com to make it a little more app-like. Feel free to create issues on this repo for feature requests of any kind. However, some features may not be possible due to the way this application is working. Also, I don't want this to be a feature bloated monster, but a slick and small app.
