I know the planet screen is rather full, but there's absolutely no mention of any Trade income.
I have to go out and go into Govern > Trade just to see the detail.
To make room, Population & Food could be combined on one line.
e.g. so it shows 9.5 / 11
Then the tooltip would show what both current tooltips currently show for each.
Then you have a spare line to add Trade in there, along with a detailed tooltip for it
