Greetings everyone! I have to say, I love the tech tree, however, it can be a bit daunting for me to keep up with. Firstly, I think it might be helpful to have a research adviser that chooses what technology to pursue, where you tell him your desires in broad strokes. "I want expansion" will cause him to focus on social structures such as farms, as well as scanning and drive technology, etc.
Also, I am not sure, but I think if scientists finish the work they'd researched, even if they were only a sliver from success they simply stop where they are. It would be nice if they either immediately worked on something else, where you could queue research much like you queue buildings, or if they 'banked' their research, representative of the scientists relaxing and taking a break after their success, returning to their research with a refreshed, invigorated mind after you choose another project.
