i have not been able to figure out how to hide the quiver/ammo pouch on hunter or for any free space to not be included.

help please - thanks ;)

The servers are down for maintenance so I can't test, but there's code to display free and total space for each bag type, and an option on how to display it. Look for "show bag type icons" in the config. For the classic fork, I'm not able to open the config, I think because a library it depends on is broken.
