Another thing that I have done is to create a user specific column in the sheet, where you are displaying your detail view, to hold a choice value of All or Favorites. Then you can create two lists, one with no filter for ‘All’ and one filtered by the isfavorite or like column for ‘Favorites’. Then set visibility to show either list depending on the choice selected.
There is a similar example in the first tab of this app:
