I would like to suggest that there is a setting for you being able to hide buildings you already have upgrades to in the building menu, to decrease lag

I don't get any lag in the building menu? Are you maybe on an old computer/phone/device? I have every building unlocked and have the resources to build them all on united earth. Maybe have a filter on (a category or a search) if it's lagging you
it when you scroll down fast, it lags...

Well just search for what you need?
Having just the upgraded buildings reduces clutter and even in categories with a large amount of buildings it can be hard to find the building. Also, you may need it for searching up a building, or you are browsing for options

There should be an option to hide premium buildings if you dont have premium
