Hello,
when you start having 15-20+ Colonies/ ships it becomes really difficult/boring to manage all ships and planets. I really love to micromanage everything but atm is a burden.
A possible solution would be able to sort planets/Ship. It would already be helpful if you could sort planets after name/size/manufacturing production/science production/economic production etc.. The same for ships and maybe also having the possibility to group ships together, so not to have hundreds of single ships in the list.
Another thing really needed imho is a small windows in the planet management that shows exactly all bonus/malus of that planet (including the bonus/malus from the colonizing event).
Pretty please ? 
PS: Another thing I would really like to have is the possibility to choose a series of tech (also from different branches) to research one after the other, so that no reseacrh points go to waste. Now i think it is only possible in the same "branch", but with the problem that if you select a tech after a "specilization" one (the ones with 3 options) it will always select the first one form above.. which sucks :/
