<p>The My Snippets plugin allows you to define custom widget content on a per-post basis from the edit post screen.</p>
<p>While the plugin is both simple and powerful, it’ll never replace such plugins as Widget Logic and Widget Context nor is that the plan. What it does is allow you to add custom widget content from the edit post screen without having to go to your Widgets screen in the admin for additional configuration.</p>
<h3>Features:</h3>
<ul>
<li>Post-by-post (or any public post type) widget content that you control.</li>
<li>Extra widget for use on your site.</li>
<li>Easy-to-use snippets settings box on the post editor.</li>
<li>Supports HTML and shortcodes.</li>
</ul>
<h3>Professional Support</h3>
<p>If you need professional plugin support from me, the plugin author, you can access the support forums at <a href="https://themehybrid.com" rel="nofollow ugc">Theme Hybrid</a>, which is a professional WordPress help/support site where I handle support for all my plugins and themes for a community of 70,000+ users (and growing).</p>
<h3>Plugin Development</h3>
<p>If you’re a theme author, plugin author, or just a code hobbyist, you can follow the development of this plugin on it’s <a href="https://github.com/justintadlock/my-snippets" rel="nofollow ugc">GitHub repository</a>.</p>
<h3>Donations</h3>
<p>Yes, I do accept donations.  If you want to buy me a beer or whatever, you can do so from my <a href="http://themehybrid.com/donate" rel="nofollow ugc">donations page</a>.  I appreciate all donations, no matter the size.  Further development of this plugin is not contingent on donations, but they are always a nice incentive.</p>

Smart Custom Fields

GUIでカスタムフィールドを管理するプラグインとして必要な機能を満たし、かつ軽いです。また、他のプラグインでは有料オプションであるサイクリックにフィールドを増やす機能がデフォルトでついていて助かります。
