Add more incremental research between and along major unlocks

At the moment researching things mostly leads to a giant pile of new buildings and occasionally vehicles that you have to put a lot of effort into constructing and organizing before you get any benefit. Research thus ends up feeling like more of a waiting period between deciding to start on a project and actually being able to work on it, rather than something worth doing passively.
The only benefit from doing more research in the short term is having more shit you need to deal with, rather than anything actually getting noteably easier, except the researches that increase the vehicle cap.
If there were more researches in between the major unlocks that simply did small improvements: Such as mildly increasing the housing provided by settlements, minor belt and pipe speed increases, truck and storage capacity increases, etc. It would help make research feel like less of a chore and more of a beneficial thing to invest ongoing time into.
