The chat thing might be tricky because of how it works when you're a spectator, which is technically the case when you're picking your planet. I'll see if I can come up with something that doesn't suck.
The idea of being able to preview the state of surfaces is great. I might overhaul the entire picking interface and see if it's possible to use the tag preview renderer feature in a different context somehow.
Thanks for the feedback Sir_AL!
