I’ve just submitted my first ever plugin to the WordPress repository. It’s called Text Beautify and can be found at the following URL:
http://wordpress.org/extend/plugins/text-beautify/
The purpose of the plugin is to beautify post titles, post contents, and comments of your WordPress blog. In post contents and comments, the text is made sentence case. In post titles, it is made title case, so all words are capitalized except for a user-defined list of exceptions, such as: of, an, the, etc. It is really targeted at persons with a refined sense of text aesthetics and people who just want their content to look nicer.
