In the above settings you can choose to show the Chart Column and Highlight Bar (Candle) Tips which by default are green for a drift and red when shortening (wrong way round imo - a traffic light is red and the top, amber in the middle and green at the bottom).
In the Settings >> Edit Settings >> Ladder Editor >> General Tab you can change the default 'Highlight colour for price move - Up, Down, No move', the default colours also being green for a drift, red when shortening and amber yellow for no price move. However if these colours are changed (I prefer the opposite - green when shortening, red when drifting and amber yellow when no price move) it doesn't change the 'Highlight Bar (Candle) Tips' which I think would be a nice cosmetic addition - it could even also have the 3rd amber yellow colour for when there is no price move but still show the bar tip as amber yellow by default to show there are incoming bets matched for the no move same price.
So this suggestion is that the Highlight Bar (Candle) Tips colours match the 'Up', 'Down' and 'No Move' price highlight colours even when changed.
Only a tiny suggestion compared to some of my others, but a nice bit of cosmetic screen consistency and tidying up
