<ul>
<li>All the contributors, translators, and people leaving comments, 
bug reports and suggestions on the official page and in the

</ul>
<h3>Plans for the next versions</h3>
sooner:
<ul>
<li>manage media tags for all selected attachments</li>
<li>audio and video preview on editing screens</li>
</ul>
later:
<ul>
<li>phpdoc all the functions</li>
<li>more detailed description for file_gallery_shortcode function 
(what can be used in ‘orderby’, what do ‘columns’ mean) for beginner programmers</li>
<li>yoxview lightbox http://www.yellow-llama.com/yoxview-gallery-wordpress-plugin/</li>
</ul>
maybe:
<ul>
<li>show attachments’ Custom Fields in the main page of Media Library (custom column)</li>
<li>media library sort by file size or picture dimensions</li>
</ul>
probably not, but who knows:
<ul>
<li>watermarking – probably in another plugin…</li>
<li>when detaching / deleting attachments, just remove them from DOM 
without refreshing the entire file gallery box, but take care of 
originals and copies</li>
</ul>
And thank you for reading this 🙂
