Just wondering whether you get a kick from using GNOME BOXES virtualization in your GNOME Shell or Shell extension development. I think I saw some conversation about it somewhere but couldn’t trace it again. Or maybe it was about something called running a “nested GNOME Shell”.
Otherwise, in case you have some other agile deploy-debug setup recommendation that doesn’t involve both restarting and occasionally crashing your own desktop session that you work from, happy to learn about it.
