Add the ability for us to fully customize and create new layouts from scratch.

Current options are not customizable at all; these are predefined layouts by Restream, which are sometimes okay, but more often they do not work for the on-screen elements.

We would like to see options to resize and set them, just like we can do with widgets. This is something other players supports - copy the option from them.

The current layouts are not sufficient. Often they are not capturing what (at least I) want to display on the screen in the way I prefer.
