With surface labels turned on, the surface labels on the moon are extremely cluttered.
It would be useful to have a name density slider (like those for stars and deep sky objects) to reduce the number of labels to a managable number.
It would also be nice to have different sized fonts for major vs. minor features, which is the usual practice on maps. For example, Mare would have a larger font than tiny craters. Currently all the labels look the same.
