Using NameStack

[Hornetzero]

So, I was seeking an addon for blender 2.79 that could assist with advanced bone renaming, including armatures, bones and constraints, automatic name generator. I found this:

nameSTACK [1.02.20]

nS [stack_demo] A simple outliner like layout, gain quick access to object and object datablock names, offering quick selection, find and replace and more advanced batch naming options. Many features yet to come! Purchase ($4.95): Grumroad Blender Market

Unfortunately there is no videos or online assistance with how one can use this addon and I was wondering if anyone here knows how to use its renaming functions?
