systemdgenie VS Tabby

SystemdGenie is quite nice.

Not exactly what you're asking for, but maybe this will suffice? https://github.com/KDE/systemdgenie

There is systemdgenie. It has a kind of pseudo-repository (here) with a link to another repository. I call one repository 'pseudo-' (and it is here) because it has no issue tracker and because it seems to direct one, via a link, to another repository; but the link is broken. And when I try to install the program, using the instructions and code on the 'pseudo-repository' (which does contain those things), a seemingly essential step in the process (the one starting cmake -DCMAKE_INSTALL_PREFIX - I can't give the whole command here because it breaks Reddit's formatting).

I would be using Tabby Terminal.

tabby.sh - design, features

iTerm2 is a great terminal for macOS. I use it extensively every day. Despite that, I would gladly try out other terminals because it's fun and because I'm always open to finding something superior to even the great tools I use.

That said, there is exactly 1 feature that seems to only exist in iTerm2, and until another terminal emulator appears that has it, I'm staying put: tmux control mode.

I've found Tabby does a good job and is Cross-Platform to you can use on Windows too. It can run any installed shell, serial connections and ssh. You can create profiles. It needs some work to be fully functional in Wayland i.e. Autohide feature doesn't work. But that's a graphical issue. Though, if you're just after creating and organising SSH profiles not terminal emulation, Remmina already has you covered. SSH, RDP and VNC.
