When you have a lot of metaboxes in the post/page edit screen, you end up scrolling which is confusing. Metaboxes 
represent a group of fields like Address, or Ingredients, etc. Imagine you are creating a deep CV for a person. 
Suddently you have <code>Addresses</code>, <code>Contacts</code>, <code>Profile</code>, <code>Education</code>, <code>Skills</code>, <code>Languages</code>, etc. But as you can see 
 Addresses, <code>Contacts</code>, <code>Profile</code> can be categorized as `Personal Data.
This plugin lets you group metaboxes by anything, just name each metabox as <code>Tab / Box name</code>. So the 
 Addresses metabox should be named as <code>Personal Data / Addresses</code> and it will be grouped with <code>Personal Data / Contact</code> 
under <code>Personal Data</code> tab.
Notes:
<ul>
<li>Both <code>Tab / Box name</code> and <code>Tab/Box name</code> or <code>Tab/ Box name</code> work</li>
<li>Built-in metaboxes are ignored (they usually sit in the sidebar and are needed all the time)</li>
<li>Although tested on 3.2, it should work since 2.5</li>
<li>Javascript enabled is required</li>
</ul>
