MCFE Arborist is the glue holding Family Edition together.

It...

Resolves the three-willow, two-walnut naming collision across Hexalia, Hexerei, No Man’s Land and Bountiful Fares by declaring them distinct species (Goat, Weeping and Peach Leaf Willow; Black and Brazilian Walnut) that match how they actually look and behave.
Builds in resource and data packs at TOP priority, always active, carrying 502 language overrides plus recipe and worldgen unification.
Modifies entities such as ants, flies, wasps, and mantids to match the modifications provided by Realistic Bees.
Adds a whole host of floating plants to Through the Lilypads, Gently for natural plant movement in boats.

Adds a variety of recipes for peaceful gameplay, including a "stardust" system for explosive Nether Star generation, ghast tear creation, blaze rod ignition, and phantom membrane melting.
Also adds "Vegan" recipes for cactus leather, mushroom meats, seitan meats, and more, such that a player can live the Roots dream of killing nothing.
You still have to put in quite a lot of work, though...

Soon adding:
Salt compat
Daily quests compat
An overhaul to the custom brushing system which will create per-player instanced loot from brushable blocks outside of the vanilla suspicious blocks supported by lootr
An overhaul of the Beginner's Delight village generation to allow for the old radial villages it used to support but with the new terrain respects (and I'll be talking to the developer, love that mod...)
Several other big compat fixes.

Basically, this is where I put fixes that can't go into another mod. Things which grow into something which should be a seperate mod get moved there, like Loam and Vessel, Chickensshed Reforged mod, or MCFEndIsland
