It’s not much, but it’s a start. I put it on GitHub in the hopes that someone else might want to improve/play around with it-- so you can look at the code if you’re so inclined. It’s limited to what the public API can do, so it’s very simple. I’m hoping BunPro will open up access to more in the future.
Let me know what you think!
