Set Aside lets you change the post format on all posts in a category. This should come in useful e.g. when you used to run a theme that styles posts as “Asides” based on categories, and then you switch to a theme that styles them based on the post format, a feature which was introduced in WordPress 3.1

Set Aside

Change the post format on all posts in one category. Useful when you switch from styling "Asides" based on category to the new post formats.

Aside widget allows a page or post to insert arbitrary content into a 
sidebar (or other dynamic widget area), supporting something similar to the 
typographic notion of a ‘pull-quote’.
Aside widget is triggered by the presence, in those pages which require it, 
of one or more ‘aside’ custom fields with values that specify the content 
of one or more widgets. Shifting the locus of widget content control from 
the widget to the page makes for more natural authoring of conditional 
content which needs to be associated with just a small number of pages.
As well as text, an ‘aside’ custom field may contain HTML and/or PHP code. 
Of course, any HTML should be crafted so as not to break the containing 
page structure. PHP parsing must be explicitly enabled in the widget 
administration panel and any PHP in the ‘aside’ field value must be enclosed 
in the usual tags for it to be recognised.
A little bit of short-form magic can be triggered by formatting the aside 
field value in the following way.
<pre><code>{#|!|!!}id[,prefix,suffix]
</code></pre>
A value of the form #id (e.g. ‘#232’) causes the the page or post 
identified by the integer id to be used as the widget content.
A value of the form !id (e.g. ‘!myasidediv’) causes the contents of the 
HTML DIV identified by id to be used as the widget content. The selected 
DIV must reside withing the current page or post. Normally, the selected 
DIV is removed from display within the page proper, but a value of the form 
!!id causes the DIV to remain in the normal page flow. Processing of page 
content for the identified DIV is unsophisticated: the DIV must not itself 
contain any other DIVs and the DIV id attribute must be the first attribute 
after the tag name.
Prefix and suffix can be used to specify arbitrary text/HTML which will 
be used to bracket the selected widget content. PHP can also be used, but 
will only work if parsing is enabled as described above.
<h3>Examples</h3>
A few examples of the use of magic values in the ‘aside’ field.
<pre><code>#232 
</code></pre>
Display page 232 in the aside widget.
<pre><code>!mydiv 
</code></pre>
Remove the contents of <code><div id='mydiv'>...</div></code> from the current 
page and display it in the aside widget.
<pre><code>!!mydiv 
</code></pre>
As above, but leave the content in the page.
<pre><code>!!mydiv,, 
</code></pre>
As above, but style the widget output in some special way.

Aside Widget

Display arbitrary sidebar content conditional upon a particular post or page.
