Hypothetical situation: You have modded Component A to require both Tech A and Tech B. While playing your mod, you have researched neither tech A or tech B. When you right click on Tech A in the research queue, it says "results: none."

Now wouldn't it be cool if it instead said: "Further gains in this research area first require research in Tech B."? I do. Question is, would this be hard to code?
