@A.Winge Uhh, methinks there is something like that already in the game, its rather hidden in under
Intel section where there's a tab
Planets [2] and I can confirm because I'm looking currently straight at it, the new tab section I mean. Since I've explored and surveyed many planets in star systems I've been to which is about 5-15% of the entire medium/normal sized game's star map already, which surprisingly feels like I've explored more than that and in a good way, doesn't really bother me as much if I start running into similar planets but fortunately with the way SS is built up it's probably a more easy thing to "fix"/add down the line by making or altering a few existing 2d planet art (
which seems to be a case already) with slight different craters and landscape areas and atmosphere effects and size if it has any to making a few unique planets like bombarded and blown in half types of planets or massive objects and thus implementing more variety along with text.
Sorry, got derailed with my own thoughts, I was going to say that it does list the surveyed planets and by clicking on one you can even take a peek on planets you haven't surveyed or visited yet thanks to it bringing up the on-screen chart of which planet is closest to furthest of its star along with showing which planet has orbiting moons. Though it does seem to be in a state of disorganized as I can't tell just by looking as what station orbits what moon or planet, or what moon/satellite is orbiting the closest to its SOI (Sphere Of Influence).
The surveyed planets do have the info about what you found there, the info is just hidden under the icon tags the same way if you're in a shipyard main screen where on the right upper area has tags and straight to their left of the screen is stability levels and a number.
The new surveying aspect of the game could perhaps use a bit more flavor in a form of text or just different planetary art of your crew performing EVA mission on a surface that looks similar to what is seen from space aka the object the player is using survey on but at this point I'm just guessing and thinking out loud as I'm finding it rather hard to find flaws of the game, explains why I like playing SS from time to time again and again. The only major thing I find lacking is the current absence of Nexerelin, I'm a new Nexerelin junkie and I need my intake of that fix!
