It is not uncommon for webmasters to simply comment-out code for text they do not want to appear on the page. In general, this is the wrong approach to take for Manifesto, especially when it comes time to upgrade, and your carefully-commented text files are overwritten by new files.

The correct approach is to use CSS to hide content. Virtually every piece of text built-in to this system can be specifically identified by a CSS selector. Use the display: none; command to instruct browsers not to display elements you want hidden.

For example, if you don't want categories displayed in the Features section of the homepage, you could use a selector like:

div.m_features h3.category {
 display: none;
}

and categories will not appear. This change is will persist even if the feature_home.inc file is updated.
