Why is the basic workflow of the modern-day programmer split over multiple tools and over multiple systems?
Aspects of Github could be modularised and added to the editor while still keeping the underlying tool simple and this could change our user experience for the better.
Imagine flipping through your pull requests in the text editor and then seeing your friends comments and code reviews appear on top.
Imagine an issue being created on Github and the file(s) referenced instantly glowing.
This opens doors to thinking about the engineering workflow in a new holistic manner.
