[Interface] Highlight interactibles on map

I find myself zooming out to the cloth map to check if there is anything of use nearby, and I find myself doing this alot. Things that are worthwhile often stand out, but sometimes do not, like the wrecked wagon pickup. A button that when held caused the grid square they are in to highlight, perhaps with a red or blue faint glow, or perhaps even colour coded to the type of thing it is highlighting, could be useful. This is only for the 3d map, the cloth map is clear enough.
