This plugin gives you the ability to automatically generate a title for your post, when upon publishing no title has been given.
<ul>
<li>The title is generated by the first sentence of the post;</li>
<li>Few simple settings on a dedicated page will allow you to specify the criteria for this to happen (see <a href="https://wordpress.org/extend/plugins/autotitle-for-wordpress/screenshots/" rel="ugc">screenshot</a>);</li>
<li>It naturally influences what the permalink will be like (if you use <code>%postname%</code> in it);</li>
<li>You can decide to generate a title also when editing a post, again if the title is deliberately left empty.</li>
</ul>
This plugin is a must if you use WordPress posting content in one click and not looking back, and, in general, if you do not want –or care– to give titles to your posts, but you want the post permalinks to be a little more meaningful than just numbers.

Autotitle for WordPress

Generates a title upon publishing a post, if no title is given. Optionally works when editing posts as well. It is a must when posting in a hurry.

This is a tool to understand your rewrite rules (“Pretty Permalinks”). It is indispensable if you are adding or modifying rules and want to understand how they work (or why they don’t work).
It is only an analyzer, it does not change any rules for you. It parses the rules down to their components and shows the connection with the resulting query variables. It allows you to try out different URLs to see which rules will match and what the value of the different query variables will be (see screenshots).
This plugin was written as a tool to help answering questions about rewrite rules on <a href="http://wordpress.stackexchange.com/" rel="nofollow ugc">the WordPress Stack Exchange</a>.

Monkeyman Rewrite Analyzer

Throws a warning if WP_DEBUG is on, other than that still a very handy tool to check your rewrite rules.
