Well, I could be wrong, but I think it's more than just the Chess.com end. Your software program (e.g., SCID, Arena) would also have to recognize those arrows and load them. I'm not quite sure that the arrows would load, at least in SCID. You can draw arrows in SCID as well of course, I'm just not sure if it's programmed to recognize arrows drawn in external editors or not.
Drawing arrows in game editor


But you idea is a sound one and should be considered as a serious thought and a good one. It gives more freedom to do as you please
Maybe you will have to work out how to do it if you feel so
Good luck
Hi everyone,
I think chess.com has a fantastic game editor that allows you to annotate your own games and copy them in pgn format, which I can then go through in a pgn reader (separate software).
However, I think it would be a great improvement if the game editor allowed you to draw arrows, highlight squares etc. I understand this is possible in "analysis board" but not in game editor.
If it were possible in game editor, I could then copy the pgn and go through the games in my pgn reader, and see all the arrows, highlights etc.
Any thoughts on this?
