Hi @Incivtus Thanks for the URL, I have looked into your store and found what you need, you specifically need that all the products should have their different page and url but it will show in a bunch if their variants has open, You can achieve it with Metafield, but you need to change a lot of things in your store theme files.
I would suggest you to keep using the App, as it is free and fulfilling your needs.
I didn’t get your point, when you are saying you need to hide color picker, Can you please explain that, so that if there is a workaround for this I can explain you that here itself.
Hopefully it will help you. If yes then Please don’t forget hit Like and Mark it as solution!
Best Regards
