Just like how pages are referenced differently from blocks, whiteboards should be referenced differently from pages
It could still be double square bracket but it could look a bit different (whiteboard icon or something)
I have pages and whiteboards that are the same or similar name and it would be nice to be able to tell the difference when looking at them, like in the screenshot
I tried whiteboards today and for me it was a sketch I would have liked to reference from within the page it links to
