Frame on picture in picture

When we use a camera feed as a picture in picture layer it sometimes in unclear visibly that that image is actually separate from the full screen behind it. I’d like to see a way to attach a simple line frame (in color if possible) to just that picture in picture layer. Such a frame needs to resize and/or move along with the layer.

Thanks @jimowens,

We’ll consider your suggestion. In the meantime, if you need to see where the border is, click on the PiP layer to highlight it. You’ll see a green frame that will separate it from the main layer.
