Feature Request: Document method functionality in detail
The current documentation simply reiterates the name of the action. What would be helpful is to explain with much more detail the process of the method/function. 

- explain what object types it expects, what it WILL and WON'T work on
- how to use it
- how the action works

Something like:
'Loops through all Layers - selected and unselected - on all Artboards on the current Page, copying any Styles in a separate linked Library to the current Sketch file and setting each Layer's Style to the Style in the  local file.

- Expected input: **Single Selected Page**     
- Affects: **Text Layers, Object Layers**       
- Ignores: **Local Symbols, Library Symbols**'
