It is a nice and lightweight mod for players that are looking to add a little extra to the vanilla game without to much overhaul.
I think this could be a nice start for a nice mod, There are plenty mods that add similar stuff to factorio. I would suggest to add what tiers of random items you are adding in the modportal, so people know what they're getting.
I don't know what your intentions are with this mod or where you want to go with it. but i can see some potential in it when you continue to expand or grow it and maintain it.
I like it and i'll keep it in my modlist.
