Automatically converts post and image titles to title case.
<h3>What is title case?</h3>
Title case would convert any of the following:
Let’s go to the market 
Let’s Go To The Market 
let’s go to the market 
LET’S GO TO THE MARKET *(except for this scenario — see below)
to:
Let’s Go to the Market

*Originally, I had coded in a way to handle acronyms so that “LET’S GO TO THE MARKET” titles could be converted to title case (note that acronyms are automatically preserved in all other cases as long they’re already in uppercase). However, it wasn’t very ideal. A bad solution for an extremely rare problem. So, if you have the rare problem of having all uppercase titles that need to be converted, I can still help with a custom/manual solution, but I decided against it being in the plugin officially.
<h3>Additional Notes:</h3>
<ul>
<li>Once activated, Auto Title Case will update all new and existing titles of pages, posts, custom post types, images, etc. Whenever making such bulk updates to the database, it’s recommended to first make a backup.</li>
<li>For new image uploads, the titles and alts will be generated from the filename. This, along with using properly keyworded filenames, is good for SEO. Bad: DSC_0001.JPG. Good: lets-go-to-the-market.jpg.</li>
<li>Currently only supports English. Non-english titles will convert all words to having their first letter capitalized (Vamos Al Mercado). With enough demand, and maybe some help, additional languages could be supported.</li>
</ul>

Auto Title Case

Automatically converts post and image titles to title case.

Scott Weaver

Puts a drop-down under your post title titled “Change Case,” which gives you three options:
<ol>
<li>Title Case</li>
<li>Lowercase</li>
<li>Uppercase</li>
</ol>
Selecting any of these options will immediately change the title text you have entered according to the selected setting.
