I’d like to be able to edit all the CSS files via the WP Theme editor rather than missioning with DW via an http://ftp..
Just so much quicker and easier, but also because I’ll be handing the site over to the client who might want to tinker a little and won’t have dreamweaver..
Can you add that in somewhere so those CSS files also show up in the WP editor?
Not that I know of, but you really should never touch any of the theme css files for any reason. All changes should be done through either the Quick CSS in the Styling tab or the custom.css file in the css folder.
You can use free programs like Filezilla and Notepad++ to edit things locally and then upload via FTP which is pretty standard.
