I was creating link posts on http://www.bilalakil.me’s Twenty Fourteen happily 
until I was nonplussed by the doppelgängers that made themselves apparent 
when I added the theme’s also-impressive Euphoria widget to the mix, displaying links.
I was seeing the same posts displayed twice on the front page: 
once in the main post loop; and again in the Euphoria widget!
To solve this problem I decided to exclude posts with the link post format 
from the post index page’s main query, 
and thus this plugin was born.
The plugin’s settings sit neatly on the Settings > Reading page.
You can find this plugin at: https://bitbucket.org/bilalakil/formataway

Formataway

Formataway lets you exclude selected post formats from your post index page's main query.

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.
