Great tool

This plugin was precisely what I needed. Thanks!

Only concerns are:
(1) This plugin leverages Mozilla PDF.JS framework. As of 2015-NOV, this plugin is significantly behind the present version of that framework:

Plugin Settings page states:
PDF.js	Version	Date
Stable	1.1.1	18 Mar 2015
Beta	1.1.114	7 May 2015

PDF.JS page states as of 2015-NOV:
Stable 1.1.366
Beta 1.1.469
<a href="https://mozilla.github.io/pdf.js/getting_started/#download">

(2) The plugin apparently supports additional presentation options from the framework but such are not documented in the plugin literature.

For example:

* page: page number. Example: page=2
* zoom: zoom level. Example: zoom=200 (accepted formats: <code>[zoom],[left],[top]</code>, <code>page-width</code>, <code>page-height</code>, <code>page-fit</code>, <code>auto</code>)
* nameddest: go to a named destination
* pagemode: either "thumbs" or "bookmarks". Example: pagemode=thumbs

In use within WordPress:
