well, I'll put these two first, as it's what my former tribe were waiting on..who'll prob not return now because they've found other interests.

1. Planting/crops
2. Cooking

for me

3. Archery/shields
4. Mounts
5. Make crafting more detailed (see below)

I'll explain last one a bit. Make something like bone gauntlets, require leather gloves/bracers as base, which then bonecrafter/armorer adds bone to, of course using other items like screws etc. This would include more crafts in the final product also giving finished product more variety of different stats and/or skill bonuses.
