You cannot change the map here. That you'll have to do with the Intermediate Map Editor.
However you can draw regimes and hex libvars on the map over here. Also you can set Victory Points (VP).
A list of all VP placed on the map. In case you forgot where you placed them and to avoid you having to click all hexes.
Scroll down the list to find total VP on map.
Allows you to remove or set VP to a hex.
Once you have selected something to draw (see #4) then you can click hex by or hex to change the hex to a value… OR use this fill mode which will set all the hexes with same value around the selected hex to the new value you are drawing with.
Will open a popup where you can pick exactly what you want to draw on the map.
Always click here after drawing otherwise next time you click the map you'll inadvertently change it.
