The purpose of this plugin is to minimize page load time and resource usage by updating the page title and content only rather then reloading the entire webpage. 
The new contents and titles are fetched by ajax calls.
Restriction: 
As the rest of the page like header including all styles and scripts, footer and sidebars are not affected, you should only use this to switch between pages with the same overall layout and requirements.
You can enter shortcodes in the page content that will show up as a button or a text link. 
When activating the link, the pages title and content will be replaced by the title and content of the specified page.
There are four possible independant arguments to the shortcode: 
– page (required). This can be the page title or the page id. 
– text (optional). The button text or textlink text. 
– title-elm (optional). The title element id or class if it is not the default as entered on the settings page. 
– content-elm (optional). The content element id or class if not default.
Examples: [pla page=”Tet page”] [pla page=”5″ text=”Go to the testpage”] [pla page=”My Page” content-elm=”#my-div”]

Page Load Ajax

This plugin enables the use of shortcodes that create links to replace the current page content with the content of another page.

Turn sticky (featured) posts on and off with 1 easy click! Control permissions with “User Role Editor” provided by <a href="https://sethcarstens.com" rel="nofollow ugc">Seth Carstens</a> and <a href="https://sethmatics.com/" rel="nofollow ugc">Sethmatics</a>.
This plugin is probably the most simple from the SM plugins collection. However, its usefulness and time saving features make it very powerful. Many themes and plugins use the “sticky” option in WordPress either to move a particular post above other posts, or to “feature” posts. An example is that a good deal of themes use “sticky” posts to populate a “featured posts” slider on the homepage of the blog. Quickly turn posts sticky status on and off with 1 click.
Features include:
<ul>
<li>uses builtin WordPress functions to reduce any possibilities of conflicts with other themes and plugins</li>
<li>a nice looking star icon uses AJAX upon click to immediately save your posts sticky status</li>
</ul>

SM Sticky Clicky Star

Honestly built the plugin and then didn't use it for a while. Had the need for it again, still works (wow!) Simple and elegant.
