extend replay controls

• “Jump to start of next/prev round”
• “Jump to move number X”,
• “Jump to this player’s next move”

@coyotte508 could be something for the framework?

I mean, it depends where the controls are added. If it's on the overlay or if it's on the playerboard.

IIUC, it can only be on the overlay. How would it work on the playerboard?
