The Picks settings tab controls who can see what before games start, and whether the commissioner/managers can place their own picks in the pool.
Pick visibility
Two options:
Visible — other members can see a pick as soon as it's placed
Hidden until game start — picks stay private until that game locks (kickoff/first pitch), so nobody can copy a live pick. This is selected in the example screenshot.
Manager picks
A toggle (off in this example) controlling whether managers/commissioners can also submit their own picks into the pool, separate from members.
Commissioner can view member picks
A toggle (on in this example). When enabled, the commissioner can see members' picks before they're revealed to everyone else — described in-app as: "When on, you can see members' picks before they're revealed to everyone."
