So I think I’m two years delayed here, but this is amazing and showed me a completely different way of thinking. @hbowie I followed most of your instructions from 2022, but I did this via the Query > Favorites, so I assume that some of the menu changed since then.
If I’m following this to a logical end, one could create a custom web page of any design, on their own, to serve as a navigation start. This completely changes how I’ll save favorites as now. Wonderful.
