It would be nice to have a copy-able pgn of analysis board positions, if at all possible.

Do you mean
1 ) FEN of the current position,
or PGN of
2) whole game to current position
3) end of played moves to current position
or
4) something else?

I could use 3) above, as I often play through the most likely (IMO) moves,
so it would be nice to copy paste that analysis to my notepad.
