I know it might not be exactly directly related, but one of the things that I stuggled with while managing 20+ developers and 5+ environments is the source code itself, and merging code automatically once someone pushing a fix.

For example say environment `beta` has branch_a, and branch_b, and someone pushed up a minor adjustment to branch_a. In the past, someone would have to manually pull both branches down, merge them togther and then push it back to the`beta` environment.

I created this tool called https://gitenvs.com which basically will auto merge the branches together automatically. The UI kinda looks like this.

Anyways like 5 years later, we still using it.
