Make the PIP movable. Currently, as it just sits in the bottom right of the screen all of the time on the Icons, there are layouts that it covers up another site. Twice today, we had that happen and we did not think someone was dialed in and we found them behind the PIP.
If you can't move it around, then just make the bottom right part where the PIP shows blank. If the PIP is turned off, that rectangle stays blank and when the PIP is on, it covers it.
