48) A small nice-to-have tweak: The ability to add a short note to each colony that can be viewed and edited from the civ manager report screen. When I've got a lot of colonies, I sometimes want to note things like "Build nav center here when possible", or somesuch.
48a) For bonus points, have the population column on this report show the maximum population as well as the current population.
48b) For more bonus points, add hover text to the columns of the report, showing the same breakdowns of approval and other values that you can get from the planet's detail page.
48c) For yet more bonus points, allow the columns of this report to be resized and selected from a larger list of available columns, to show things like intrinsic bonus, starbase bonus, influence generated, rally point, enemy agent presence, etc...basically any info available on the planet. A column showing the icons for any bonus tiles on the planet would also be great.
48d) For a final bit of extra credit, merge in some functionality from the planet list, so that you can see information on enemy and unowned worlds, to the extent available given current intel levels, etc.
