When planning a new trip‌ I frequenty find myself flying around with Simulator just to have the beautiful visibility that TerrainSafe offers. I live near the mountains and it's often hard to see with the normal map how wide valleys at a certain altitude are and which valleys are well connected to each. Just the other day I went from Munich to Basel and had to find a good route under Zurich CTR. 
W‌ould it be possible to enable TerrainSafe in planning mode as a simple overlay? This shouldn't be too much work since it's already implemented and it would make planning so much easier. 
T‌hanks!
