Whilst looking for hidden collectables today, I thought it would be nice if there was another way to find them, than just the fairy fire buff that shows them all.
How about adding a speciality for an explorer / geo, or a new search that identifies a collectable on your island, and flags it the same way as the fairy fire does, but just for one item. Flag remains for 5 minutes as it does now.
Would give them something else to do that also helps with collectable quality of life, but not break anything?
