Option: displaying last move w/ move number rather than mark

[artasparks]

Right now the last move is indicated with a mark. Consider adding an option to support marking the last move with the current move number

That's a really good idea. Why didn't anyone think of it earlier? :)

It might even be good as a default marker.

One caveat is I don't think it makes sense for all widget types. It definitely makes sense for game reviews, but I don't think it makes sense for problems and the board-editor.

Thus, this will probably end up being a widget-contextual option with override possibilities.

I'd like to see it as an option even for problems, as Graded Go Problems for Beginners numbers moves and refers to move numbers in its commentary.
