Woud love a toggle/setting for some components that allows them to be sticky to the top or bottom of screens. For example on mobile it would be great to have a set of sticky actions at the bottom, or a set of tabs that can be sticky on scroll at the top. Maybe there’s a rule that you can have max 1 sticky header and footer component on a screen so it doesn’t go crazy? I think there are lots of use cases for keeping something visible while scrolling content behind it.
See screenshot as an example of an app I built with a set of action buttons at the bottom. Would love for those to stick in the footer regardless of the length of content and other components on the page.
