Released a new version
Wrote JavaScript
I released v0.2.0 of sb-atom-sonic-pi, which supports Sonic Pi v4.0.

Due to the server now verifying the token of the GUI, I need to implement a full client for Sonic Pi for it to work. Luckily, the Sonic Pi team has made a boot daemon and an API which makes it much easier to boot and handle the Sonic Pi server. I've ended up partially recreating the API in Javascript for the package.
