JQuery Hover Footnotes lets you add footnotes with qualifiers of you’re choosing, then dynamically displays them on hover-over. So you can easily add footnotes to a post by wrapping them in qualifiers, then they will dynamically display in a jQuery hover popup when the user mouses-over the footnote link. There is also a settings page where you can change options like the footnote formatting.
Features
-Numbers, Words, or ANSI characters can be used as footnote reference marks 
-Footnotes can be superscript, subscript, or normal text 
-Footnotes can be placed in page footer or hidden 
-Popup/Hover footnote can be turned on and off.
Usage
To anchor the footnote reference mark/number, use {{FOOTNOTE_NUMBER}}. Then just embrace the actual footnote text with double brackets [[FOOTNOTE_NUMBER]] Footnote text [[FOOTNOTE_NUMBER]]. The footnote text can be placed either inline or at the bottom of the post, the plugin will find them and auto place them in the footer area.
So this is what you would write in the post window…
This is my post and I want to add a footnote{{1}} in the text. By default it will appear as a superscript.
[[1]] My Footnote. [[1]]

This plugin allows references and citations in your posts. If you find issues or if you think it lacks some features, please contact me.
To use it, simply add your reference using a shortcode you can choose (‘zref’ by default), and a item ID (a reference ID from a Zotero library you have to declare in the admin part if the plugin).
Because it’s a minimal implementation, you need to add the reference ID manually in the code. Maybe later I’ll do better 😉
Then a list of all references will be added automatically at the end of the post.
Here are some examples:
<ul>
<li>[zref]VP5PKI56[/zref]</li>
<li>[zref name=’numref’]VP5PKI56[/zref]</li>
<li>[zref name=’numref’ /]</li>
</ul>
You can optionnaly add a name to the citation, so you can reuse it in your post. Important note: the displayed attributes will be the attributes of the FIRST reference with that name. Any other attribute will be ignored.

Zotero Notes

This plugin adds references and citations functionalities (in a wikipedia-like style) from a Zotero account.
