Hi, Zordiak here! Just wanted to make a quick note that I am also the creator of WoWTokenPrices.com so check it out sometime if you haven't yet.
StayUnsheathed uses a timer that checks to see if your weapons are out and if they aren't out it takes them out. Update: I have now added the benefit of event-driven toggles. These forced sheath toggles should fix the problems that the add-on was having before. It will remain more consistent now.
Simple, just install and use. Just checks to see if you have your weapons out every few seconds if you don't it pulls them out.
HOW TO TURN OFF SHEATH SOUNDS:
1. Keep in mind that you are modifying game files. This is against TOS so take caution when you do this.
2. I can't reliably keep up to date instructions for how to remove sheath sounds so I would recommend doing a Google search for "How to remove sheath sounds in wow 6.1" replacing 6.1 with the current game version. Remember google is your friend.
