I would love an option to research to the halfway point. Something to prompt me to change research once I pass 50% progress on my current research goal. So many times I get some research going, intending to stop at the halfway point (because I anticipate the eureka moment occurring soon), only to find that I've forgotten and I'm now about to finish the full research right as I also achieve the eureka. This is very frustrating and feels like a significant loss of progress. Loading an autosave half a dozen turns back is a pretty meh solution to this issue. Obviously I could just be more diligent, but this would nonetheless be a very nice quality of life improvement.
