Support for Focusmate.com

We have a community of people doing virtual co-working together on Focusmate.com and it would be great to enable them to use Piper to float their partner's video on top of their work during the session.

Several people use Google's Pip extension already on Chrome but your solution looks great for Safari too.

Thanks for your consideration! I know the community would appreciate it 🙏
