I am using Ubuntu 20.04 with Gnome on my main computer, which has this sidebar on the left side where I see currently running applications or pinned applications (no idea what that's called, the launcher?).
On my secondary computer I have to use openSUSE for different reasons, and I'm also using Gnome there. On the openSUSE machine, there is no such permanent sidebar. I can only see a similar menu (though not over the whole height of the screen, the top and bottom is empty) when I click the "Activities" button in the top left corner of the screen.
I'd really like to have an Ubuntu-style dock/launcher/whatever on my openSUSE machine, but I can't figure out a way to do that. Is that a Gnome setting I can just change? Is there an additional package that I need to install to do that? Can I even do that without removing openSUSE and installing Ubuntu?
