The UI allows you to easily navigate between branches and files in repositories. It also makes it easy to share your changes with others by providing pull requests from within the app itself. I dislike that sometimes, after updating my system software (e.g., Windows 10), I cannot access some of my team's repository folders or even log into them until I reboot my computer. This can cause problems when working remotely where rebooting is not practical. We are solving two separate issues here - one being sharing our work amongst our coworkers/teammates, while we're all located at different locations. And another issue is how easy it is to collaborate amongst ourselves without having to email everyone individually asking about their progress.
