Is there any chance you could make the "only extension" to be all 4 tiers after Legendary? I like this mod, but, I feel like dealing with 5 different sub-tiers of each tier is a bit much and will be very hard to organize and sort when recycling and uptiering or even just straight crafting, (So many filtered inserters....) but only having 2 new tiers is not quite enough. I feel like, for me, the perfect balance would the top tier of each of the new ones you made. The icons you used for the "quantum" tier also fit really well and I love them, but the stars not quite so much. Any chance for also maybe an alternative set of icons for stars? Other than that, I think this is great.

Do you mean adding only 4 new quality tiers to follow Legendary? So 8 qualities in total?

Yes, there are many qualities. It is intended for playing with a high chance of higher quality. Without other mods, no one will probably reach maximum quality.

All the icons were drawn by me or slightly modified from the original ones. The stars aren't exactly great, but I ran out of ideas.

I'll try to think about it and make another "config mode" that would behave differently.

Yea, 8 total. I didn't know about changing the chance, yea that would probably be needed with so many ha ha. Thanks though.

Ok, I'll add about 5 new tiers. I plan to redo the whole mod in the next version
