New interaction for popup: preloader

Hi bricks team,

I’m not sure if this is a logical solution to creating a preloader. But it would be great if we have an interaction for the preloader. So we can create completely custom preloader using popup.
(The popup is displayed before the screen is fully loaded and is hidden immediately after it is fully loaded).

I think even page transition will be possible easily by creating animation interaction for pop-up.

Please note that page transition and preloader are two popular ideas in bricks ideas.

thanks
