I'm curious. If you now need to use planetary scanner just to see the planet/moon in all it's glory in the system map is this a sign of more to come with the system map. I don't see the point in having a planetary map instead of a grid sphere when you can still see land bases and your icon on both. What extra functionality apart from graphical does the full glory planet visual give you ?
They give excellent clues on where to find geological features.....at the very least. BTW, you need a DSS to obtain info on whether a planet is volcanic or not.
