It would be nice if various tailored themes in Porto, Tucson, Tahoe and Dixit could be selected for each user. The concept would allow admins to define/build the site layout and controls using the installed theme packages and then "publish" them in a UI control for users or select roles/groups to choose from. This would create a more personalized experience for the end users and create a way to visual represent group or team sites. Of course that comes with more work for site admins, designers and testers, but the users would love it.
I would take this suggestion over to https://dnncommunity.org/ as this would be a core feature.
