Does webstorm plugin sdk provide an api like custom "formatters" like Chrome (v47+)

I am using https://github.com/facebook/immutable-js.

in Chrome, I can use https://github.com/andrewdavey/immutable-devtools to inspect formatted data structure of immutable.js.  When I use immutable.js in node.js, I want to develop a similar webstorm plugin to achieve same  result, so I can format object in Debug window
