I have an idea that is a little bit diferent but could help in this matter:
We could have a log of the discoveries that we already found like a "Simmilandpedia" or something like that. But this feature should only catalog the discoveries already achieved because most of the fun in this game is to find new things and sort out how they are done!
Some discoveries are made by accident, like the lightning rod and the vaccin that are discovered in a whole different way as these doesn't involve inspecting anything.
Discoveries may also have some other discoveries as prerequisites so you should explore the game further in order to find them.
But a log of what you already found would be great indeed! Nice one Mackaa!
I'll post this in the Suggestions topic.
