Page-list is an awesome plugin for WordPress that makes it easy to embed hierarchical lists of pages within a page.
Suppose, for example, you have a page called Countries and then below that pages like United States, Canada, etc. Rather than having to update the Countries page with links to the subpages, Page-list will let you embed that list automatically.
The short code
[subpages] will list all pages in the hierarchy beneath the current page. You can also specify variables to expand or limit the depth of the hierachy displayed. For example,
[subpages depth="1"] will only show a list of pages directly between the current page, while
[subpages depth="4"] will show all pages up to four levels deep underneath the current page.
This makes it much easier to use and manage pages within WordPress.
Posts By Tag is a plugin for WordPress that makes it easy to insert lists of tagged posts into pages and posts.
For example, I have dozens of posts tagged “Batman.” With the Posts By Tag plugin, I can insert a list of all posts with that tag by using the short code:
[posts-by-tag tags = "Batman" number = "999"]
This will insert a bulleted, hyperlinked list to all of the posts I’ve written with that tag.
WP-Inject is a WordPress plugin designed to make it easier to find Creative Commons licensed images into blog posts.
… the plugin adds an easy to use search metabox to your WordPress editor (“Add New” post screens). Simply enter any keyword to find great photos for your post.
Advanced users can head to the WP Inject settings page and fine tune the plugin. A lot of different options let you control most aspects of how WP Inject finds and inserts images into your posts. By editing the templates you can control exactly how the photos and automatic attribution will look on your blog!
Even though I’ve been using it for years, I didn’t realize until recently that WordPress compresses uploaded images to 90 percent.
The WP Resized Image Quality plugin adds an option in Settings that features a slider so you can change the compression level.
I get why the WP devs probably think compressing uploaded images is a good idea (they are wrong, but I get why they think this is a good idea), but compressing images and not building in a setting where this can be adjusted without adding a plugin or editing a PHP file is ridiculous.
Threads is a plugin for WordPress that makes it easy to arrange multiple posts in a timeline. If, for example, you had several posts on your blog about a particular event, Threads makes it easy for readers to follow along.
Another good usage of Threads is on a news site to track posts related to a single ongoing story. For example, a tech blog might create a thread to group stories about a product launch event. Several months later, stories about sales figures for the product might be added to the thread. By placing all of these posts in a thread, there is a useful visual way of browsing all of the posts.
Developer Alex King has a nice example on his website of the sort of potential use for this.
