We have a mix of developers on the team. Some live in the terminal. Others see git as a black box that occasionally breaks their work. The terminal-only developers kept doing git merge master and hoping for the best.
GitHub Command Center gave the visual people a different path. They could see branches, commits, and conflicts as a graph and fix them by clicking buttons instead of memorising commands. The terminal people used it too, for rebases and history inspection that are easier visually.
The bug isn't git. The bug is the tooling gap between how git works and how humans think. Visual tools bridge that gap. The team didn't need to learn more git. They needed to see it.
