What is new about the Start menu in Windows 10 build 10036

In earlier builds of Windows 10 such as build 9926, there are 2 Start Menus. One of them which could be activated with a simple Registry tweak and was resizable. The other is the "Continuum" (Tablet Mode) Start menu. But this ability is not present in the freshly leaked Windows 10 build 10036. The previous Registry trick does not work, so you only have the new Start menu, which can be switched to a full screen mode.

Windows 10 Build 10036 features notable changes to the UI

New screenshots of Windows 10 Build 10036 have leaked to the internet which showcase some changes which should be visible in the upcoming build for Insiders. The major change (but not the only one) is the network selection pane is now more compact compared to Windows 8/8.1. However, it is created in Metro/Modern style and is probably built on the WinRT/Modern apps API. Let's see what else has changed.
