Instead of having highlighted item, why not use a search feature, when you happen to go on a tile where there is dirt and a shovel or a barrel, it's obvious there is something there, you just have to use search.
But you could make riddle out of it, like a soldier who lost his precious family sword, near something, your party could search a tile to find it, or even ancient artefact, or lost key to a dungeon (you would have to gather hint from npc..etc)
Or finding some gold or old equipment or anything(or nothing of course) on random tile, by spending some in games minutes (10min) ?
I Could find it quite fun to try finding/resolving some riddle by gathering hint.
