Would be nice if there was an option to display coordinates in every square. Thank you.

That sounds like a great idea, that will be very helpful to those unfamiliar with the coordinates

I will change the option "Show coordinates inside the board" at lidraughts.org/account/preferences/game-display to have the effect that each field is marked with its coordinate individually

Can you please use coordinates where the x axis is marked by letters A to J and y axis is marked by numbers 1 to 10.
Moves will be marked by (initial square) -> (final square).
I don't understand the idea of counting the squares.
Chess moves are not annotated as 1 to 64 squares where each move is (first number) -> (second number).

@RoepStoep It hasn't been done already right? Thank you. I can wait.

@Hangrad The numbers are the official notation, you can't just change that. So you need to get used to it.

I have understood this: memorizing the first 10 positions (the squares from 1 to 10) it is easy to improve by counting, for example, from the square number 1, +10 to obtain the square number 11; + 20 to obtain the square 21, +30 to obtain the square 31, +40 to obtain the square number 41. And so on... For example starting to the square number 7 I obtain +10 the square number 17, +20 the square number 27, +30 the square number 37, +40 the square number 47.

I think as MxN board sizes gain acceptance, eventually algebraic notation will also gain acceptance.

All notation in studymaterial like books, games, websites etc. is written in this notation for hundreds of years. I don't think it is a good thing to consider a different notation. Also, when you analyze just one game in a whole from a book, you will get used to it very easily. Learning to play the game is a lot harder!

@BumperBalloonCars I would like to ask you to reconsider avoiding using a new notation. For thousands of years chess used descripitive notation.
en.m.wikipedia.org/wiki/Descriptive_notation
It was recently changed to algebraic notation.
en.m.wikipedia.org/wiki/Algebraic_notation_(chess)
That can be one of the main reasons for a recent increase in popularity of chess.
Currently, draughts are very far from chess in popularity. You should consider trying a more convenient and economic notation. This may increase the number of players here. To be fair, I have never seen any checkers or draughts book in a book store. However, there are plenty of chess books. The most popular ones use algebraic notation. New players find it much easier to use algebraic notation compared to descriptive notation, Only very old people still use descriptive notation. They play far less than young people.
Learning to play chess is much harder than draughts. There are many different pieces, each moves differently, many special rules like en passant and castling. Draughts rules are much easier and faster to learn to beginners compared to chess.

@Hangrad I understand your perspective, I really do as I come from a chess background as well. It takes some time to get used to, but you will!

Consider the disconnect this will create between lidraughts and literally all other draughts theory, information and puzzles out there...

Maybe they could have made a better/easier choice a couple of centuries ago, but we cannot rewrite history really. Convincing the rest of the world to adopt a different system is not a thing done easily in the 21st century, the stars would have to align to make unicorns come down from the sky first!
