I don’t know about games. Steam stuff is supposed to work but it’s something I do much anymore. I was referring more to casual use, Web browsing, streaming, emails. Ironically Linux now seems more suited than Windows to people who use computers for simple stuff.
There are a lot of things that try to replace FancyZones but I don’t know that any do well. There are gTiles and Linux PowerToys if you haven’t seem those already. I’ve never searched for alternatives to VS or Teams.
