    Git GUI Client

    ...It's too late to start up, falls well, is user registration tedious when downloading, is paid for commercial use, is not multi-platform, or is an animation or visual effect. It was said that the production was overkill and the wizard and the source code were not published. I tried to eliminate such inconvenience as much as possible. At first I started developing it for my own study, because I was interested in learning how to use Git and how it worked inside. Some of the best engineers of the time may think Git in GUI. That's a lot of it. When I want to execute a command that I rarely use, I sometimes force myself to do not rely on the GUI, open the terminal and hand enter the git command. ...
