It would be nice to see a tech tree list so we know our guide to a certain technology we want to go in.
Tech index is helpful in a sense that you can get the information on the current technologies you have and look at what unlocks them. Though this process becomes tedious and you might overlook some research that you want to plan on getting for the future technologies. The display for Tech index is somewhat helpful being alphabetical but it doesn't really help a lot unless you've researched a ton on one of the research and you've decided that path.
Suggestion:
A Tech tree list (sort of like what most mmorpg skill list does) would help guiding our nation to a certain technology we want to receive and could have a drop down menu/pop-up menu of the requirements we need to get for it.
