Any chance LichessTools allow you to style the analysis board engine arrows based on a centipawn loss threshold relative to the best move? Either only show arrows that are within a certain centipawn loss of the best move, or fade them out to disappear or be thin by a centipawn loss threshold? If not, is this easy to do with something like tampermonkey? Thanks!
The [Lichess code](https://github.com/lichess-org/lila/blob/d163dd0cef6cb340be38a70f51d07a44093be4ac/ui/analyse/src/autoShape.ts#L142) will calculate the winning chances changes for each engine move and show the ones that don't change them with more than 20%. Based on that percentage it renders the size of the arrow (rounded to a value from 2 to 12).
The code is not something I can overwrite and it doesn't preserve information related to centipawns or even that winning percentage.
Moreover, there is a design reason why the value for width is integer and capped between 2 and 12. CSS style rules are based on the fact that arrows will have a specific set of sizes.
So the answer is no, it can't be easily done, if at all. The only thing one can do is display a completely new set of arrows based on the values in the computer eval object.
Ah, that's too bad. Thank you for the detailed explanation!
