It's no secret that Supplementaries and Quark look great together and are the base for any Vanilla+ build. I think I have a great idea for compatibility that will complement the mechanics that already exist in them. You have a wonderful hourglass, while Quark offers interesting mechanics with gravitation sand. So let's combine them!

1. Gravity sand can be placed in an hourglass
2. The gravitational sand in the hourglass is moves in the opposite direction
3. Instead of starting with the minimum signal and gradually strengthening it, the gravitational sand in the hourglass will start with the strongest and weaken it as it moves upward

This is just a small, pleasant addition. But it seems to me that this is the idea of Supplementaries
