Some questions

Hi there,
a few questions in one post:

1. i changed the theme colour blue in the theme options as main colour for another blue colour, but the icons and everything are still the wrong (old original) colour. Which part of the style sheet can i change or is there a better way?
2. The editor misses a few options, like the Row container, the revslider and the btn option. Why is that? The rest is there….
3. how can i remove the line, below the menu?
thx in advance
Tim
