src/stores/useWindowStore.ts:39

• The clearWindowsByCategory helper function deletes windows but doesn't clean up the associated state in minimizedWindows, maximizedWindows, and restorePositions. This could lead to memory leaks and stale state when windows of the same category are reopened. Consider cleaning up these related states for each deleted window ID, similar to what's done in the closeWindow method.

const clearWindowsByCategory = (
  windows: Partial<Record<WindowAppId, WindowInstance>>,
  category: WindowCategory
) => {
  const idsToDelete = Object.values(windows)
    .filter((window) => window?.category === category)
    .map((window) => window.id);

  idsToDelete.forEach((id) => {
    if (id) {
      delete windows[id];
    }
  });
};
