I think I asked about adding this feature a long time ago. It would still be helpful.
Could we please have the star tags we have added to letterboxes show up on the list created by a search even when mapping the area? See this example? It would be so much more helpful to know which clues I've already read and chosen, and which ones are left over? The map is very helpful, but you have to be able to get through the whole list in one sitting, or else guess where you left off, especially if you're trying to collect clues for just one area, like just north of a particular highway.

Thanks!
