Recently I found myself in an end game situation in which I had researched virtual dust (or something) and had built the convert all excess food into industry building. This however stopped all population growth (as I would expect) but this became a problem when I moved farther down the colonization tech tree and opened up more population limit increasing buildings. This lead to the troubling fact of having over 1000 extra food and 20+ population slots open but zero growth.



Thus my suggestion to allow the toggle of improvements so that you don't have to scrap and rebuild them if you want a certain bonus or not. This would also help with the viability of most of the trade improvements. I find it disconcerting to have a mega power house corporation hero and a system that has 5+ trade routes only to lose all of them to a war and bring my dust production from +200 to a massive negative.
