Hearthfire allows you to purchase land and build your own home from the ground up - from a simple one-room cottage to a sprawling compound complete with armory, alchemy laboratory, and more.
Several Weapons and Armors have bad or inconsistent properties (e.g. Orcish Waraxe considered to be made of Iron, 2-Handed Sword considered a 1-Handed Sword for perks purposes, etc.). This mod (in theory) fixes them all.
This mod comes with a script that will automatically unequip arrows when you unequip your bow and will equip the same arrows back when you equip your bow again.
