So, to who is interested: I published the source code so far for Gitte, a new GNOME Git GUI. Just be aware that this is still subject to rapid change since I am very early in development. I also don't have an application icon, yet (I can't do artwork, even if my life was on the line).
Also: remember, this is OSS. No warranty. No entitlement to anything. 🫣 That said, feedback welcome. Just create an issue 🙂
