Where is the number of captured shown?

Unfortunately nowhere. I implement it ASAP.

And information about komi, please.

What opcion or command I must used to list all player per country in one single roster or list? Secondly, Where is the number of captured shown in chess pieces including clear board or to change position boards?

As far as I know, you can only sort by gametype/rating and alphabet.

Secondly, Where is the number of captured shown in chess pieces including clear board or to change position boards?

You can look at the 'list of moves' to see captures (x) and if needed go back to that move to see what happend. There is no fast way of seeing all the captures (afaik).
