Configuration

Disable any stat via tui.json:

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": [
    ["opencode-stats-for-nerds", {
      "show": {
        "cache": false,
        "activity": true,
        "model": false
      }
    }]
  ]
}

All options default to true except thinkTime and activity.
