Many moons ago there was a field to name the planet. I think it disappeared when the new version (now the old version) was built. There was also once a field to label the fleet you sent out. I bet those fields are still there and just need to be displayed, unless you re used them for something else.
I already like the "custom query builder".
What would be really cool is to divide the pl up into groups. Like maybe dividing pl into risk of being taken, so I don't overbuild a pl that I know is going to be taken. Really it's because I'm usually high when i play and I forget. So if I could label a pl then I might remember.
What would be super super cool is if the program warned me when I was going to build on a pl that I labeled as risky. There are probably other warning you could set. But that's probably too much, and it might also be too close to having the computer do the work.
