Interface

I think it would be a good idea to create the one topic, where users present their own suggestions about interface changes.

There are my small suggestions:

1) Possibility to setup numbers (1-8) on left side of the chessboard (or both side).
2) The more clear figures and letters. (boldface font)

(ps. I hope that you will understand my easy english ;) )

lichess.org/account/preferences/game-display

Select what one of the options ... Board coordinates (A-H, 1-8)

On the options you can set board coordinates in three ways: none, outside or inside. You can NOT set numbers on LEFT side of the board (or both left and right) , also you can't set letters on top of the board. (or both top and bottom)
