I use WinSCP for some of its amazing benefits. I connect to my FTP server with WinSCP and let it monitor my local folder /website/public_html.
Any changes I make in my local folder automatically get uploaded to my FTP server by WinSCP. The feature is called Keep remote directory up to date:

As for SCSS, I also use it:
I have a script that opens a console window to watch my /website/scss files and compiles them to /website/public_html/styles/. WinSCP sees the CSS file has changed (or is new) and automatically uploads it.
Notice: The only downside is you cannot reach your error_log as that is automatically generated on the server by PHP. To do this you can easily instantiate another WinSCP to connect to your website. Now you have 1 WinSCP monitoring your local folder and 1 WinSCP where you can access your site map.
