Sidebars, Popovers, and Modals

Recently, I’ve noticed the need to move from sidebars, to popovers, to modals. For example, in the WordPress block editor you can add blocks from a small and quick popover called the Quick Library, or from the larger Sidebar Libary. And, there’s been a few designs floating around that use a modal to browse patterns.

I wondered if there was a way to ease the transition between these different UI’s and came up with this animation.
