This plugin will make developers and site builders (hopefully very) happy.
It enables site administrators to supply additional styles or/and scripts to 
be loaded alongside the theme’s resources. It will work regardless which 
theme the site is running, which makes it brilliant for adding custom 
programming and content blocks.
Styles and scripts can be either entered manually or loaded from 
external URL’s.

Custom Resources

Easily load additional styles and scripts (for both front and backend pages). Works by direct inline embedding or by using URL's.

Front-end Editor is a plugin that lets you make changes to your content directly from your site. No need to load the admin backend just to correct a typo.
It makes the same <a href="https://codex.wordpress.org/Roles_and_Capabilities" rel="nofollow ugc">capability</a> checks, so that if a user isn’t allowed to edit something in wp-admin, they aren’t allowed to edit it in the front-end either.
You can edit posts, pages, custom post types, comments, widgets and many <a href="http://github.com/scribu/wp-front-end-editor/wiki/List-of-editable-elements" rel="nofollow ugc">more elements</a>.
Goals:
<ul>
<li>save as many trips to the backend as possible</li>
<li>compatible with any theme, out of the box</li>
<li>light and fast</li>
</ul>
Support and development:
<a href="https://wordpress.org/support/plugin/front-end-editor" rel="ugc">Support</a> is handled by the lovely <a href="https://wordpress.org/support/profile/designsimply" rel="ugc">designsimply</a>.
I am not developing the plugin anymore; only applying the patches that other people send via <a href="https://github.com/scribu/wp-front-end-editor/" rel="nofollow ugc">Github</a>.
