Admin Menu Slide is a simple plugin that adds a feature to hide admin menu and make it slide when hovering on the edge of the screen. Works exactly like WordPress collapse menu – you can toggle the feature on/off by clicking a button, which is at the bottom of admin menu. When enabled, admin pages have full screen width.

Admin Notice is a very simple plugin that allows you to display custom notices in the WordPress admin that is visible to all users.
Control over the notice text and styling is available from the plugin’s settings page.
Developers can use the <code>admin_notice_enable</code> hook to control the notice’s visibility on a more granular level. The following example demonstrates how to show the notice only in the “Posts” area of the admin.
<pre><code>add_filter('admin_notice_enable', function($enabled) {

 $screen = get_current_screen();

 if (isset($screen->post_type) && $screen->post_type !== 'post') {
 $enabled = false;
 }

 return $enabled;

}, 10, 1);
</code></pre>
