The addon is pretty simple and light-headed. It's main job is to keep the amount of reagents you specify it to and purchasing the missing once when you visit a vendor that sells them.
Making this into a routine, you simply walk over to a reagent vendor and talk to him, the next second the addon has refilled you with the lacking Ankhs, Candles or Symbols and you can fly on where ever you like without having to count and think about the reagents!
I did a complete rewrite of this, so I might have forgotten to add some coma somewhere but don't worry -I am working to fix this and make it a wanted addon for the people that like to keep it simple!
