Suggestion: when using the option to display voices in different colours it would be handy if the little orange voice indicator next to the caret when inputting notes would also change color when switching voices. Especially when there are more than 2 voices in one stave. Maybe even the complete grid that’s showing the position could change colour, so it’s not to be missed 
IIRC This has been suggested, but when I think about it, in dense music this might make the caret harder to spot; so some other way of indicating active voice might be better.
Dorico already shows you both the voice direction and its index at the bottom left-hand corner of the caret. We don’t plan to change the colour of the caret. But thank you for the suggestion!
