BottomSheetCoordinatorLayout

24/11/16 This is not a fully working implementation

An attempt to use Coordinator Layouts in Bottom Sheets! There is also a question on Stack Overflow that is yet waiting for a decent answer.

Custom behavior	(Issues)
✔️ nested scrolling works	❌ toolbar sometimes collapses too early
✔️ toolbar can be dragged	❌ toolbar cannot be collapsed through drags
	❌ main coordinator layout consumes some scroll

Android default behavior (unsupported)
❌ cannot close by nested scrolling
