Request demo line option for new lines

[Jonathan003]

I like the use of arrows to preview moves in new lines, like it is done in Chesstempo. Chesstempo also has some other interesting option for these arrows to. Like "candidate moves as arrows when not training". For when you have more than one candidate move for your side. Chesstempo is free for basic functions. You can make a free account to see how it works. I have made a small video capture so you can see how it works.

I have a maximum of 3 candidate moves for my side in any given positon. So if I don't train the two other candidate moves than I would see two arrows if I enable the function "candidate moves as arrows when not training".
This function is intended for if you have more than one candidate move for your side, not for the multiple candidate moves of the opponent.

Actually I like Chesstempo more as Chessable. But there are allot of useful functions missing.
