Web Animation Application

It would be great to have a separate app for animations. Something similar to the discontinued Adobe Edge Animate: https://m.youtube.com/watch?v=Ayi_JBA6oi8

A powerful app that can open/import HTML pages to animate DOM elements using the timeline and JavaScript actions.

This could be an extension of the amazing Bootstrap Studio, and enable us to create truly engaging web content without relying too much on external JavaScript plugins.
