Hover cards switch

While enabled, hover your mouse over a user’s name within PeepSo community whether it’s in posts, comments or a tag, and it will display a beautiful Hover Card that represents a short summary of the user. For mobile experience Hover Cards show when you tap on a user’s name. First a Hover Card is shown, then from there if that is not enough you can navigate to see the entire user profile.
