When you add this plugin, a metabox is added to the edit post/page screens that allows you to disable ShortCodes in that one particular post/page. Admittedly, this plugin may not be widely needed by the general public. However if you are a plugin developer or documenter, you might find it very useful.
If you want to show examples of how to use a ShortCode and not have that ShortCode activate upon display of the post, this plugin will come to your rescue. The SCuD will disable all ShortCode processing for any post.
SCuD is written to prevent any collateral damage. After the post content is displayed, it activates the all previously disabled ShortCodes again. This allows any ShortCodes that you may be using in sidebar widgets to process correctly.

SCuD – The ShortCode Disabler

Allows you to disable ShortCodes on a per post/page basis.

Evermore automatically abbreviates all posts when they appear on a multiple-post page such as the main blog page. It has the same effect as putting <!–more–> after the first paragraph of every post. All formatting and HTML tags are preserved in the abbreviated post.
If the post already has a <!–more–> in it, then this plugin does nothing to it and the existing <!–more–> will behave as usual.
If you want to disable the plugin for any specific post, then include the codeword <!–nevermore–> in the post. This won’t show up in the post, but it will prevent the post from being abbreviated by Evermore.
To change the length of the preview that Evermore creates, log in to your WordPress administration console and go to Settings, then click Evermore. You will see the Evermore configuration screen where you can set the following options.
<ul>
<li>The number of paragraphs each preview should contain</li>
<li>The minimum length of the preview. Sometimes, the first paragraph of a post can be very short (just a short sentence, or a picture). This option allows you to add extra paragraphs to make the preview a more reasonable length.</li>
<li>Where to put the “read more” link: either at the end of the last paragraph, or on a new line by itself</li>
</ul>
