Nope, not getting any of that. If it ever existed, it's another casualty in the war on configurability. There's an option to add more space between the icons, but they're still as tiny as they ever were.
By default there are only 2 densities, but there used to also be a "Compact" option which was removed. I believe it is possible to still enable this, though it is officially unsupported at this point.
