‘Pages and Posts in Feed’ is a simple plugin that modifies WordPress RSS feed to include both ‘Page’ and ‘Post’ types in the site’s feed. This creates a site feed with both pages and blog posts in it. Useful for those who use WordPress as a CMS.
The plugin needs no configuration. Just activate it, and you are good to go. Deactivating the plugin restores RSS feeds to their default state.

Just One Category will cause WordPress to display on a category archive page 
only those posts which are direct members of that category, i.e. this plugin 
will exclude from that category page all posts which belong to any of that 
category’s subcategories but do not belong to the category itself.

Just One Category

On a category's archive page, displays only the posts directly in that category, not in any sub-categories.
