The waterfall toolbar should extend toolbar class

[A Sajadi]

Hello. It seems the main class of this library is extending from androidx.cardview.widget.CardView class. Therefore it's not an actual toolbar and cannot be used in coordinatorlayout alongside with scroll or recycler views. I had to do abnormal usage of paddingTop in xml of those views in order to prevent toolbar overlap.

Hi there.

As far as I can remember, it's not possible to achieve waterfall effect by extending toolbar. I think toolbar shadow is not dynamic and wouldn't change after the layout was rendered. I'm not sure this was the problem, thought. I should've documented it, but back in the day I was not a good software developer.

I've been out of Android development for almost two years by now, so things are not exactly fresh in my head, but I intend to refactor this library until the end of this year.
