Those symbols are on the map permanently now. This change would allow the player to control the display, on or off.
Per image, add to Map Layers control.
As an aside, for consistency and certainty, those buttons should all read "Show x", as opposed to a mix of show and hide.
Show units, Show Labels, Show Penalty, Show Grid, Show Color, Show Op. Log, etc.
You could potentially then remove the word show completely and give some more space to better explain "Penalty" and "Op. Log". Perhaps a small indicator light on the right that displays a color when toggled on.
Toggle on, shows the map layer. Toggled off, hides the map layer.
