Creating a Project

Click + New Project at the bottom of the list. It requires being connected, new projects belong to the connected team (the disabled button's tooltip says so).

One field: Name ("e.g. Offense 2025"). Name it for what's in it, the
opponent, the side of ball, the season. The partner is inherited from your
current connection. Click Create.

A new project starts with 0 Games and no filter, nothing loads until you pick games.
