Hi, I would like a feature that allows me to enter move ideas into my opening repertoires in a graphical manner (yes, we can already use text). If the opening were to be exported I believe the convention for annotation is to use the Δ symbol. Since CPT is already heavily reliant on arrows, then probably a dashed arrow is best, along with the ability to highlight squares. Without this option, I either have to remember to look at the text block, which I use sparingly, or have to remember why I inserted the move into the repertoire.
For a simple example, 1.f4 e5 2.fxe5 d6 3.exd6 Bxd6 (Δ 4...Qh4). Graphically perhaps, this is represented by a dashed arrow from d8 to h4, even though it is White to move.
