GMs would have the ability to create public or private tabs on the Fari tabletop that embed a particular website, effectively integrating outside webapps into the Fari interface. Players could also create their own private tabs that only they could see.
Any embeddable website (depending on that site's code) could be embedded, such as owlbear.rodeo, Kami PDFs, notes hosted on Google docs, external SRDs, and more. You can even embed Discord with the bots like widgetbot!
There would need to be some way to save or restore embeds between sessions, for ease of use.
