I tend to agree with @Illusory, although I will say part of me is inclined to think this could be solved in a different way with Embed Views in Rich Text, where you would essentially just embed a normal Table view, which should include sorting, etc. In other words I wonder if the sorting (and potentially other table-like functionality) should be added to Collections, or if embeds would be a better way to handle more extended/complex use cases. Or alternatively perhaps an option to replace the current Collections view with a table view, and all the functionality that implies (filter, sort, color)… Maybe I’m overthinking it though.
