One thing that has bugged me about Kamoso forever is how it insists on looking like a
mobile app when run on the desktop. This seems to be to be contrary to Kirigami's
reason for existence and does not showcase the toolkit's excellent convergence
This patch resolves that by using the default auto-switching feature and therefore
displays a desktop-style toolbar when run on the desktop. To improve the appearance, it
makes use of a new optional feature in Kirigami added in D23845 to center the actions
when in desktop toolbar mode.
Depends on D23845
