Add speaker notes system (proof of concept included)
Description Speaker notes provide an option to show some extra information on a secondary screen that helps with presenting. It's commonly supported in other programs like PowerPoint and Google Slides. In my opinion it's crucial to making a good presentation.
PowerPoint and Google Slides also provide preview of the next and previous slides. Tho I am unsure how hard it would be to do that for Motion Canvas and that sub-feature isn't the highest priority.
Proposed solution The feature should open a new tab with a parameter to change the selected UI to a speaker note UI. Using params over url paths should ensure that the presentation can still be exported to a HTML file.
The API could just expose a second parameter to beginSlide or it could expose a separate setNotes in case the notes should follow the animation.
Considered alternatives The alternatives to this would be having a PDF open or having notes on paper. But those options don't work that seamlessly
Additional context To ensure the feature wouldn't be too hard to implement, I did a proof of concept to check the viability of BroadcastChannel in a React app. However, I do not have enough in-depth knowledge about the structure of Motion Canvas to implement it right now in the actual application.

The code for the example is split into two parts, the Observing and Source components https://gist.github.com/Wokarol/2f219a69e94d9701676a205003ee288e
The components use Mantine and should be self-contained. Also, as seen in the video above. This approach should work no matter the order at which the pages where loaded.
Of course, if need be I can help with implementation (If I will be able to)
