[Suggestion] -- Show relative frequency of move played in the opening book

[tpalam1]

Hi,

As it stands the Lichess opening book is fantastic and easy to use. However, one change that I would like to see is displaying the relative frequency of the number of times move X has been played, alongside to the current raw count. Attached is a photo of the opening book currently.

I feel this would be a good addition for two reasons:

1. In most positions there are a few good moves and many bad moves. Thus, displaying the relative frequency would help players discern which variations. For example, in one variation of the Vienna Gambit, it shows that within 450 000 Lichess games played, roughly 80% of the them have only followed the top 3 moves, despite the opening book showing the 12. This uneven distribution is better represented through percentages rather than raw numbers.

2. As of the time of writing, the Lichess opening book features a nice summation row at the bottom, which tells the player the aggregate number of games played in position X, and the win-draw-lose rate. Thus, it doesn't seem to be terribly difficult to implement an additional column in the opening book labeled "% played", where % played = # of games / total number of games played.

Thanks for taking the time to read my suggestion.

Interesting, the % could replace the number of games, and moved to a percentage's tooltip

Implemented it this way, now.

Good idea, by moving it to a tooltip anyone who prefers the current design with the raw numbers only is satisfied as well.

Great idea!
This can filter out unreliable data if the move has been played very few times.
