What
In Factoriopedia show when an item is the rocket launch product of some other item. An good example of this is the base game's science packs. You can see that the satellite has a rocket launch product "Space Science", but when clicking on "Space Science" the only way we know that it can be obtained with launching satellites is because there happen to be a tooltip description.Why
This request comes mostly from a modding angle, where there might be multiple different types of launchable items that has different launch products. It would be great if Factoriopedia intuitively made this clear to the player without us having to add a custom tooltip for each. Of course we can also just add a tooltip, but then we don't have the smooth experience of quickly opening up the other item's page by clicking on the icon, having the tooltip on it, etc.It would also be more consistent, most connections in Factoriopedia are shown from both sides.
