Draw on the Map!
Allow us to draw on the map using some basic colors or a color wheel so we can mark down notes like good routes down mountains or food bushes or mark the difficult to see recourses on the map so we can find them later with ease. Unofficial maps are Essential to playing the game unless you stumble upon a lot of sheer luck events. Like carcass finding. We could just mark them as we find them, for people with weak PC's who can't keep maps open in the background to keep tabbing in and out can simply make their own In-Game!
It would be 2 different maps.
1 for Herbivores and all your herbivore dinosaurs would share one map that you've drawn on, and all your carnivores would share another map so that you can mark Bushes and Carcasses seperately without having to mix them together on 1 map with small icons.
You could also let this save to our client side so we could retrieve the PNG file and use it as an image to share, or to upload and replace someone else's!
Image is an example.
