Post Lockdown protects your site-critical pages and posts by disabling all non-admin users’ ability to trash or delete them. 
It can also lock pages and posts, which will disable editing of the post as well as disabling trashing/deleting.
The plugin adds a new options page under the Settings menu in your WordPress admin panel which allows you to quickly search and 
select for all pages and posts of any post type. When you find the item you want to select, simply click it to move it to the right 
box and click Save Changes.
See the screenshots for an example of what an Editor would see when they view a list of posts with some locked and protected.

Post Lockdown

Works very well, my only criticism is that private posts/pages should be lockable, ie private posts should appear in the search form.

In order to lock them currently you need to publish them, then lock/portect, and then make it private again

Update!! the developer added the minor feuature request/bug. This plugin is now perfect!

Now perfect

I think the plugin is really useful, otherwise I wouldn't have made it ;)

Great Plugin

Allows admins to protect selected posts and pages so they cannot be trashed or deleted by non-admin users.

Hikari Hooks Troubleshooter creates a draggable window with informations about WordPress hooks. It lists all hooks (actions and filters) that have at least a function hooked to them, and for each hook there’s a list of hooked functions, sorted by priority!
The window is visible only to registered users, and you can choose who will be able to see it, and set if it should be visible or not. It works in WordPress page, be it frontend or admin area.
When you are in an admin page, it also shows a list of special actions related to that specific page, helping plugin developers to attach features only to special admin pages, instead of the whole admin area! A list of all conditional tags is also available, informing which tags return true and which ones return false, for any page you want!
The list of conditional tags and hooks is based on <a href="http://bueltge.de" rel="nofollow ugc">Frank Bueltge</a>‘s <a href="http://bueltge.de/wordpress-theme-debuggen/536/" rel="nofollow ugc">wp_view_type.php</a>. The original code was translated from germany to english, and ported to a draggable window that can be moved inside the browser, minimized and closed.
The list of admin actions is based on <a href="http://playforward.net" rel="nofollow ugc">Dustin Dempsey</a>‘s Show Page Hooks plugin, and a few more hooks were added.
<h4>Features</h4>
<ul>
<li>The plugin creates a window, that can be dragged, minimized and closed</li>
<li>The window works both in website’s admin panel and frontend</li>
<li>You can choose who can see the window, while visitors never see it</li>
</ul>
The window presents many useful information for plugin developers:
<ul>
<li>action and filter hooks, and functions hooked to them, sorted by the priority they are called</li>
<li>all conditional tags, informing those returning true and those returning false</li>
<li>all actions present in admin pages, that are specific to each page, so that we can hook features that we want to happen only on those specific pages</li>
<li>actions that were run are flagged so, allowing you to know which actions are used in each specific page</li>
</ul>
