Just a quickie...
To make SciTE work with scss files (which are enhanced css files), just add the following information:
In /usr/share/scite/SciTEGlobal.properties (on a Fedora machine at least, YMMV) :
- ;*.scss to the end of source.files=
and in /usr/share/scite/css.properties the top of the file should read :
filter.css=CSS (css scss)|*.css;*.scss| lexer.*.css=css lexer.*.scss=css
