I think it would be great to have a button that would open a random quote in your files. Similarly to the random note button on the side-dock, but linking directly to a specific quote.
It would make for a more fine-grained injection of interesting food for thought to reflect upon than a whole random note.
I see that block references are only created once they are referenced, but given the internal-link-pop-up that already made selectable blocks, one might take advantage of that mechanism to pick a random block (which a quote would need to be I guess), that is a quote and open it.
Finding for example opens and highlights the match as well without having to set a block reference.
