This plugin was born out of a very simple need. Back in the day, when the wpautop filter was really sucky, I got annoyed and turned it off for my <a href="http://blog.bigsmoke.us/" rel="nofollow ugc">blog</a>. However, years later, me (but mostly my co-author, Halfgaar) got equally annoyed by having to manually type in all the angle brackets. I wanted to turn on the filter again, but I didn’t want this to affect all my old posts. Hence this plugin. See <a href="http://blog.bigsmoke.us/2010/12/09/wpautop" rel="nofollow ugc">this blog post</a> for more history.

wpautop control

Adds a global setting to turn the wpautop filter on and off. It also allows you to override this default for any post by adding a wpautop custom field …

This plugin is up for adoption.

Un-Line-Break is a lightweight plugin with a very specific purpose: Improved shortcode readability.
Normally, in the post editor, placing shortcodes on separate lines (like HTML formatting) results in extra line breaks in the rendered output, thanks to the WordPress auto-paragraph function (wpautop).
This plugin removes those extra line breaks from the rendered output so, in the post editor, you can place shortcodes on separate lines, thus making it easier to read and edit them.
It will not remove any double-spacing or <code></code> or <code> </code> tags that you have added.

Un-Line-Break

Remove unwanted line breaks from shortcode content.
