# Find the array key and then unset
return array_diff($buttons,$remove);
}
add_filter(
'mce_buttons',
'wpmania_tinymce_buttons'
);You can easily figure out the code by its class begins with mce-i-, by following it you would put the array above.
• Remove The “Add Media” Button
  This buttons appear with custom post but it has wide range of function and sometimes it is inappropriate to add irrelevant image with post. It is easy to manage images by integrating them into the template but managing photos with the Add media buttons is quite hard for developer.

• Hide Unused Dashboard Menu Items
  Every website is different in purpose, suppose post menu item is unnecessary for a site without blog. Appearance of unnecessary buttons makes too much confusion and you can remove it by adding the following snippet.function wpmania_custom_menu_page_removing() {
// remove_menu_page( 'index.php' ); //Dashboard
// remove_menu_page( 'jetpack' ); //Jetpack*

// remove_menu_page( 'edit.php?post_type=page' ); //Pages
remove_menu_page( 'edit-comments.php' ); //Comments
// remove_menu_page( 'themes.php' ); //Appearance
// remove_menu_page( 'plugins.php' ); //Plugins
// remove_menu_page( 'users.php' ); //Users

}
add_action( 'admin_menu', 'wpmania_custom_menu_page_removing' );Each line related to a specific menu in the dash board. Removing the menu actually does not suspend the permission of user it can be accessed through the URL directly. If you don’t want to have a filthy dashboard then doing this is a good idea. But if your aim is to prevent user from getting access then you just need to customize capabilities of the user’s role.  Add the following snippet to activation hook of the plugin.global $wp_roles; // global class
$role = 'author';
$cap = 'delete_published_posts';
$wp_roles->remove_cap( $role, $cap );
• Add A Hint About How Line Breaks Work In The Editor
  The built in option of visual editor is it creates new paragraph usually when user hit the Enter button. But if you like to add classic pattern then you have to hit the Enter+Shift button. This a stylish and quite impressive way but some of your clients may find it complex. There are many complain about having a wired white space in post or page after apply the same. You can add an effective snippet to your functions.php file. You need to change the value of $tip to make your author acknowledge of it.# Adds instruction text after the post title input
function wpmania_edit_form_after_title() {
$tip = 'TIP: To create a single line break use SHIFT+RETURN. By default, RETURN creates a new paragraph.';
echo ''.$tip.'';
}
add_action(
'edit_form_after_title',
'wpmania_edit_form_after_title'
);This is a nice way to leave a reminder for your clients and they will be careful about while posting or managing content on the site.
• Do Not Dole Out Administrator Accounts
  Great power comes with great responsibility. The role of administrator is enormous and it has authorization to deal with everything of the theme or site. Some of your clients may have competence to hold the responsibility perfectly but many of them may be less familiar with the interface so they should not furnish with entire power of administrator. In such situation assign them as editor and you will need to create a separate account for admin. Until your clients are ready to manage their accounts themselves, don’t hand over the credentials to them.Similarly you can get the clients the credentials and ask them to keep them safe and use them only when it is required. From previous experience it can be said that many clients will lose the credentials but this is also good for you as because the same client will hire you for getting them back and for routine maintenance. Actually you need to be conscious about the admin account as because they are related to vulnerability and security issue.
• Use mu-Plugins
  Um-Plugins/directory is another suitable option for installing plugins and fortunately many of the hackers never heard of it. The only one difference is that the ‘mu’ must see plugins cannot be disabled and by default they are active. They usually loaded quicker than other. So most important plugins could be installed here. The mu-plugins have to be created manually inside theWP-Content/.wp-content/
mu-plugins/
plugins/
themes/
...But there is only one limitation that WordPress only find the files from top and usually ignore codes that exist inside of subdirectory.  You can simply handle this issue by creating a single PHP file that will load at the top of mu-plugins. So mu-plugins could a safe place for codes that will not be accessed by author.
