In a game with no biters, hide the irrelevant research

[Saftorio]

My 7-year old son very much likes Factorio, he has asked me to pass this along:

TL;DR

Most of the military research is pointless without monsters, e.g. the artillery trains.

What ?

The irrelevant research items should be hidden. If they are a prerequisite to useful research, that useful research should be enabled.

Why ?

It costs way too many potions for something that gains nothing and that gets on our nerves too much. Also, the list is untidy because the useful research is hidden behind useless research.
