DISCORD
I have created a Discord server which people can use to report issues they find with this addon; to join, add a new server on Discord using the invite code BGKnpza.
ABOUT
While playing Classic, I noticed that the number of free bag spaces you have left isn't something which can be checked with a casual glance, so I created this addon to address that.
FEATURES
The information is displayed in two ways: a moveable frame on the screen, and on the icon for the backpack (like it is in the retail version of the game). You can click and drag the square to move the frame around, or hide it entirely by using the options window (accessed via the /fbs command). Hunters can also choose whether or not to show their remaining ammo count next to their available bag spaces, though please bear in mind that the ammunition you currently have loaded is what's counted.
