Windows 10 in Nokia Lumia 1520

My Nokia Lumia 1520 now has Windows 10. I downloaded the Windows insider App yesterday and the rest was history. Now my phone has Windows 10. If you look carefully you will see the new Edge browser and Groove music which are a part of Windows 10.
The touchdevelop is also working from the Edge browser. Earlier Internet Explorer in Windows 8.1 could not. Hence the second picture.
There are a few ways to run Touchdevelop Apps. The above method is as a Web App. Then you can make a full fledged app too. This feature has been removed from Windows App Studio.
I need to make the phone tiles better. There is no need for two mail apps in Windows 10 for example. These things I shall streamline and post a screenshot of the Windows phone if possible.

I have removed extra mail app. Included g+ app in it's place. All music and video files are in
place. Playlists intact. The second screenshot is the new index interface. It is indeed Windows 10!!

You can see Nokia Mix Radio in place of Groove Music. Also I have removed flipkart ebooks tile and put films and TV tile in its place. Films and TV app will help me in music directors videos. I have Laxmikant-Pyarelal, Kalyanji Anandji, R D Burman, S D Burman, Rajesh Roshan, Shankar Jaikishan, O P Nayyar and Kishore Kumar, Mohammad Rafi and Lata Mangeshkar videos all downloaded from Mobile WAP sites.

Also I have put Lock Screen snapshot. Windows 8.1 developed store app are working. Also one Windows 8.1 app which is not in store but in phone is not working. But another Windows 8.1 app which is not in store but in phone is working. So a dilemma here. A simple Hub App with texts is working.
