A useful plugin for developers writing SCSS. 
The plugin allows you to write SCSS directly on the server (via FTP) without the need for a local compiler.
How It Works?
Choose a source folder for SCSS and a target folder for CSS. 
Write the SCSS code in the file on the source folder, and it automatically creates a CSS file in the target folder.
What’s included?
<ul>
<li>Option for multiple source and destination folders.</li>
<li>Allows you to set a folder in the entire wp-content space.</li>
<li>Performance – only when one of the source files change – it re-compiling itself.</li>
<li>After development you can turn off / delete the plugin without fear, and all the files are stay where they were.</li>
<li>Allows you to develop a theme and plugin at the same time.</li>
</ul>
Example:
source: themes/your-theme/assets/scss/style.scss
<pre>
body {
 color: black;
 .main {
 background: red;
 }
}
</pre>
target: themes/your-theme/assets/css/style.css
<pre>
body {
 color: black;
}

body .main {
 background: red;
}
</pre>
— pay attention! 
If the file already exists in the destination folder – it will be overwritten by the SCSS file
