One thing I would love to see is simplifying the entrance to Xamarin University. For instance at xamarin.com/university you see enroll and preview, but no sign in or enter link.
Also on my profile ( Manage Subscriptions ) I see a 1 badge for Android and iOS, but no 1 badge for university thus making it appear as I don't have University. Also by clicking on University from the same screen it would be nice to enter the portal from there. It just seems more intuitive to be able to access the portal from the subscriptions tab.
There may be easier ways i'm not aware of, but I access the University classes and other pages in the portal by googling and from what I see it needs to be more seamless.
