This addon is not developed anymore.
I have changed the name and updated for Legion and up only: gmDurability
A minimal LDB plugin that displays durability, sells your junks (grey items) and auto-repairs (with guild funds or not).
It shows in a broker display compatible the lowest durability and in its tooltip all the equipment durabilities.
Requires a data broker display like chocolate bar, bazooka, ninjapanel, stat block, titan panel, docking station, buttonbin and more.
