While selecting a construction project, it would be great if the mouse-over UI would display the actual bonus that it would currently apply in a given system. For example, a system with 1 temperate/fertile planet should show +30 for the first science/industry building.

It would also be nice if the time projection would not only display how many turns, but also how much more industry is required to reduce it by a turn.

I want to learn how to do this kind of thing myself. Any help is appreciated!
