Hello!
I think it would be very helpful to be able to use different icons when adding a marker on a map.
They don't need to be complex, simple things like a cross, a circle, or a square would be enough.
Eventually some more complex ones could be added, like the marker for a house or a $ sign to mark trading posts and such. But I think flags are good for those too.
I know we can color code, but some colors aren't easy to see on some biomes.
PS. Why do Tar Pits not show up on the large map, while all other localized resources do?
