I have installed a plugin to let you customize Armor Stands! Just use a flint and right click away from the stand at first, to toggle mode. Then, right click on the Armor Stand to apply it.
Here are some things you can do with them:
- Move the angle of their hands
- Make them Invisible
- Make them hold a item straight up
- And many other things!

Thanks!
