Hello, I'm newbie at chess software and I'm searching for a multiple game viewer in same window, I want to look for example at 4 games at same time on the same window. I don't know if this is possible with some software or maybe I have to create a new one.
I want something like a PGN reader but with the capability of watch 4 or more games at the same time.

Try this:

or

ChessX only show one of the games of the PGN files, I want to watch multiple games at same time.
