This question is a highly personal one from my perspective. I haven't used the groups yet but I often toggle between six or seven contexts throughout the day and I'll give them a shot for that.
Profiles toggling just didn't work for me as it was too ... Slow for me as in I have to reorientate myself whenever I switched profiles.
Sent you the account, sounds like an exciting learning project that could turn out to be useful as a side effect! ❤️
