Marker in Graal Era Map and Arrow Marker
 

Perhaps we should have a marker in The map and a arrow marker in-game so we it could be more easy to locate our destination in game so what do you think?

What do you mean? The head icon serves that purpose on map. The on screen active marker would be helpful in game, but you could just buy a "pro" marker from Rufus' Hat Shop.

i think he means like where you tap a part of the map you want to go, and there is a little arrow pointing to where you want to go.

Oh, I see. It's like GTA. I understand.
