A day of sorrow indeed... No, joking aside. I gather most people use double click anyway, so this is a good change for that reason. I've never really understood it myself (the primary function of the left click being "select" when everywhere else it's "open" or "go to this thing"?? Alien stuff).
I'm just glad KDE listens to it's users and adapts to them. Looking forward to the release!
Writing systemd services for your containers is something yoully have to get used to with podman, pretty much. It's actually very easy with the built in command "podman generate systemd", so you can just do something like " podman generate systemd --name my-container > /etc/systemd/system". I much prefer managing my containers with systemd over the docker daemon. It's nice!
Also, podman can use privileged ports as root, right?
