KDE's Android TV alternative, Plasma Bigscreen, rises from the dead with a better UI
www.neowin.netAnother KDE project, Plasma Bigscreen, is back from the dead with a much better UI spread across the entire shell.
I ended up with a kde desktop set up that was good.
I used a mini handheld keyboard by Rii, it had a touch pad. There are many different styles of it. But with the customization kde has, I got a pretty fluent set up. It was a full desktop but almost more like android in terms of usage.
