LeafDrift

New
Leaves on windows. In rain and storms the wind throws a leaf from nearby trees against a window now and then. It sticks to the wet glass, slips down a little and drops off when the glass dries. Works on glass blocks and panes, stained and tinted glass, and other mods' glass.
A more natural fall. Leaves now swing from side to side as they come down, like a real leaf. No two fall alike: each one keeps changing how wide and how fast it swings, some spiral down, and now and then one flips over and drops. New "Swing" option to make it wider, narrower or turn it off.
Particle Rain compatibility. Leaves blow the same way as its rain and snow.
Puddles & Floods compatibility. A leaf landing in a puddle makes a small ripple and gets soaked, and leaves float at the real height of flooded water.
Weather Glass compatibility. Leaves stick to the same glass it puts its raindrops on.
New options: "Swing", "Leaves on windows", "On glass (seconds)", "Particle Rain wind" and "Puddles". All on by default, and none of these mods is required.
Changed
Leaves are about 30% smaller. The "Size" option still lets you make them bigger or smaller.
Breaking a leaf block now shakes loose 5 to 8 leaves (it was 2 to 4).
Leaves in a heap now lie on top of each other instead of cutting through one another.
Lighter on performance. Each leaf does much less work while it falls and while it lies on the ground, and leaves behind the camera are no longer drawn.
Fixed
Fabric: the mod now asks for Fabric API. Without it the game did not load the mod's textures and sounds, and leaves showed as purple and black squares.
Leaves were left floating in the air when the block under them was broken. They now fall.
Leaves that landed on a fence or a wall floated half a block above it. They now rest on top of it.
An animal or mob standing in a tree's leaves could make it shed leaves non-stop.
