I like that you've added the option to click through every phase, every combat, every special, but there is room for improvement.
You could add more dropdown options.
First selection is for phases (dropdown: phase1, phase2,...)
Second selection can be combat, special, deployment, platoon).
I'd also like to see all players all the time like this:
Top selection : phase 2 - special
Player 1: 1/1
Player 2: 1/1
Player 49: 0/1
Player 50: 0/1
That's better to find those, who didn't participate yet.
