Back when I was still on Gnome, I gave this a try and it was great - until Gnome got updated and it stopped working. And then they’d fix it, and Gnome got updated and it stopped working again. So I stopped using it because I couldn’t deal with the constant breakages. I see that they still haven’t updated it for Gnome 45, despite a bug report being opened for it over two months now. It’s exactly because of breakages like this, and extension neglect from the authors, that I’ve stopped using Gnome and switched to KDE.
KDE worked great for me out-of-the-box, so I didn’t install any third-party extensions. The only changes I’ve made is for aesthetics - moved the panel to the top, enabled a global menu and a side dock, for a more Gnome/macOS-style layout.
