WP Live Edit is WordPress plugin that enable the user to update the content, live, on the blog. Don’t waste time going back and forth between the admin panel and the site. Just update the content immediately while reading the blog post. The plugin is using WPs strict user control access before enabling this feature, so only the users allow to edit the blog post can do it.
This now works for both posts and pages.

<a href="https://codex.wordpress.org/Excerpt" rel="nofollow ugc">WordPress post excerpts</a> can be a great way to hand-craft the summary of your content. Unfortunately, writing post excerpts isn’t as nice of an experience as what you find elsewhere in WordPress. Want to include links in your excerpts, or bold some text? Hopefully you know some HTML!
Advanced Post Excerpts is designed to change that, by giving your editors an easy, intuitive interface for writing great post excerpts.
