An improve to the layout of the devtool could definitely improve user experience. Lets make sure the devtool is utilizing the space better.

The fluent API seems to try to mimic natural language, e.g.

 isThis(error)
 .UserNotFoundError(() => ...)
 .NotAProphetError(() => ...)

errorHere(*error*) uses the following construct:

 if(errorHere(error).isNotAProphetError){
   // Do something
 } else if(errorHere(error).isProphetNotFoundWithId){
   // Do something else
 }

would

`thisError(error).i

The astprinter seems to ignore indentation within multi line strings (descriptions).
E.g. when there's an example GraphQL query with proper indentation within the description the printer falls short printing the indentation properly.
