I like the new app drawer instead of the last ui which had scopes. It reminds me a LOT of the unity 7 dash. If only it had the functionality of the Unity 7 dash of ubuntu 14.04(when it came out) such as universal search(search for applications, files, contacts, music and video from local as well as online sources) it would be cool.
In fact, bringing the concept of lenses and scopes to THIS drawer makes more sense. Maybe the drawer could become the universal home scope and have lenses for different file types. This could also work for convergence and bring in a lot of the Unity 7 fans who are unhappy with Gnome3(like me) and perhaps even reduce maintenance of Unity 7 post 2021. I don't know if it is possible.. or feasible. An intriguing idea nonetheless.
