I actually want *more* Liquid Glass, which I didn't expect. More liquid movement and animation (bouncing, sliding, warping), more translucency. And more color-on-translucency, like the Focus icons in Control Center.
Yes, that's what 'reduce transparency' should do, but it didn't work as nicely as I though it should for me, so I tried each of the other settings in turn, and 'reduce motion' was the one that worked best...looks 'frosty' rather than 'opaque'. It also disables the parallax effect.
