Eons ago, there was a dockapp for WindowMaker that could capture an X11 application and contain its window within the dockapp tile. The equivalent for KDE Plasma would be a plasmoid which would wrap an application. Is there such a thing? It'd be insanely useful; I'd love to be able to capture a Chrome window as a widget on the desktop, for example; I'd be able to stick my ticket tracker view in a widget, open a ticket in a new tab, drag that tab out into a separate window. I could also embed virt-manager. But, really, Chrome would be my biggest use case; having that shared cookie and sync state would be helpful; the lack of it is a big part of why I stopped using the web widget.
