No. My personal opinion is that a chess fundamentals book is a better learning tool in order to reach the point where you do not need coordinates anymore.
The design principle of pgn4web is to focus on a minimalist chessboard and avoid any unnecessary distractions as you find in other similar tools: coordinates, arrows, excessive amount of buttons and so on.
pgn4web is designed for people that have the chess knowledge to read a chess game, following the Chess Informant style of publications (hence, for example, no ‘+’ sign for checks, no ‘=’ sign for promotions, no ‘x’ sign for captures).
I have no plans to make the display worse and cluttered for my target audience in order to help those that can’t actually play chess.
For your site you should probably use a different game display tool, there’s plenty to chose from, some certainly support coordinates around the chessboard.
