This plugin collapses and reduces the height of hierarchical category and taxonomy panels in the WordPress admin.
It always bugged me that when editing a post the categories panel took up so much height if you only had a few categories. This was also the same for custom hierarchical taxonomies.
This plugin just adds a couple of styles to your admin to override this and collapse that space.
I created an initial patch for this which, with contributions from other WordPress developers, was included in WordPress 3.5. You can <a href="https://core.trac.wordpress.org/ticket/15925" rel="nofollow ugc">see the patch here…</a>

Compact Taxonomy Checkboxes

Collapse and reduce the height of hierarchical category and taxonomy panels in the WordPress admin (not needed for WordPress 3.5+).

<ul>
<li>Add the possibility to click and drag on checkboxes to make bulk selections.</li>
<li>Add a custom class to checked row, so that customization of their look is possible.</li>
</ul>
Here are two demo styles that you can place in your custom admin CSS stylesheet (created with another plugin of your choice):
<pre><code>.row-checked {
 background-color: #BCFFBC!important;
}
.row-checked .check-column {
 background-color: #01D200!important;
}
</code></pre>
