Problem/Use Case:
The top admin bar clutters the frontend for subscribers and other roles.
Snippet:
// Disable admin bar for non-admins
if (!current_user_can('administrator')) {
add_filter('show_admin_bar', '__return_false');
}
Explanation: Shows the admin bar only for administrators.
Where to Place It: In functions.php.
Bonus Tip: You can extend this to hide the bar for specific roles only.
