// 1. Clicking an item selects/unselects it.
// 2. Multiple items can be selected at a time.
// 3. Make sure to avoid unnecessary re-renders of each list item in the big list (performance).
// 4. Currently selected items should be visually highlighted.
// 5. Currently selected items' names should be shown at the top of the page.
//
// Feel free to change the component structure at will.
