Revisit Multiple PIP, PIP custom size and placement, PIP permanence

[Zahir-Khan]

Chrome API has been updated with latest PIP feature. Here is the link https://developer.chrome.com/docs/web-platform/document-picture-in-picture

I also understand the hesitancy to write site specific code but I think giving us the option to customize under the extension settings for things like most commonly used websites like YouTube would be great.

Also I do think it is possible to give further option of writing scripts for power users so we can turn the entire webpage or specific div element into a PIP or multiple PIP would be great. (Lots of work ik and maybe deserves a dedicated issue or I will just fork this when time permits)
