Despite separate my own items and recipes into another folder i can't be sure which original code wasn't tweaked, so all features in single list:

1. Added mold for spear, double and quad knife (2 and 4 knives in one mold, last demands x2 metal)

2. Straw, thatch block. Not fully substitute for dry grass, but mostly. Drops from most grain crops. Straw skep is decoration only, put into craft slot to get normal skep. (Surprisingly straw works with aurochs food recipe from Medieval Expansion).

3. Leather preparing overhaul. Hide produce tanned hide and must be sliced into leather. Also can be sliced prepared and scraped version. Use shears for better result.

4. Add cooked in firepit egg (surely from Lazy Warlock, no needs any changes since branching). 

5. Ash (chop some wood into flinders and "bake" them), Lye (fixed in v1.2.3) and Potash making. Potash is great fertelizer, lye can replace limewater.

7. Flint saw. Crude and fragile with limited use but still saw. Slightly imbalanced because let skip reed basket storage and not essential since introducing rough doors. But i like it. Seems many have trouble with crafting it. So i'll say: You cannot CRAFT flint saw, you must KNAP it. It no needs any handle.

8.Grinding charcoal. Charcoal powder has many uses. My favorite is briquette from straw(only straw, so you need some supplies from your fields), peat and charcoal powder. It's best for bronze and copper smelting and fueling forge.

9. Composting. Mix 4 straw, 4 rot with any soil and give it some time. Fully cured compost can be used as fertilizer or for creating composted soil, terra preta and compound fertilizer. Don't mistake it with vanila compost

10. Smithing: you can forge spear heads and two knives at once.

11. "Washing" muddy gravel for limestone.

12. Fully growth "grain" plants no more drops seeds, only products. You can craft seeds from soy beans, grains, pumpkins and bell peppers.

13. Skep drops when you harvest honey too.

14. If i remember correctly, you need (until any other mods override it) knife or scythe to get straw from grain crops.

README!:
BTH is a CONTENT mod. What it means? First, it have ZERO of scripting and CANNOT broke other mods scripts. Second: it cannot affect directly any recipe except hardcoded in it (and i make or patch no recipes outside of vanilla recipe list or mod's own items). Third, it works fine despite any version differences until version directly affects crafting mechanics or vanilla items used in mod (i'll try fix all found troubles although, just PM me or make something other that notify me) so mod counts "Up to date" until some broken things will found dispite any verision numbers.

P.s. I still support mod, just not develop it further right now.
