This is a module for sStats, a data display framework.
Written for my own personal use, but saw others were requesting something similar, so I figured I'd put this out there for them. Basically adapted "Broker_Bags" to work with sStats.
It simply displays "Bags: Free/Total" for a quick glance at how many free slots you have left.
If you want it to display "Bags: Used/Total" then simply change the following line 46 in "bags.lua":
freeSlots = freeSlots + GetContainerNumFreeSlots(i)
freeSlots = freeSlots + (GetContainerNumSlots(i) - GetContainerNumFreeSlots(i))
