Editing a SCSS file now will trigger a full page reload, while before it would only update the stylesheet without a full page reload. To be honest, I prefer the old way.

Arg, I've to look deeper...

For now, I changed the styles reload task to this:

    gulp.task('styles-reload', ['styles'], function() {
        browserSync.reload('*.css');
    });

It's hacky as fuck, but gets the job done until I can think of a cleaner solution.

Thanks for sharing.

Yes, I see. The problem is that now we are calling browserSync.reload(); without stream:true parameter. In the evening I will try to change the process a bit. I got some ideas for this...

Ok, I've did a new PR: #911 which takes into account problem mentioned by @alfaproject . Now, in case of styles changes, reload is being done only to styles themselves instead of full page reload.
