Please enable playing of videos in design mode and dev mode, not just prototype mode.
As a designer,
I want to be able to include videos that viewers may play,
So that my viewers/designers/devs may better understand what I have designed.
As a dev,
I want to be able to include videos that viewers may play,
So that my viewers/designers/devs may better understand my thoughts visually
Better still, I can then link videos to take people on a narrated tour of my design.
Currently, videos do not play inline on the design, but need to pop up in a preview modal. Not great UX from a UX platform.
