Modification tool settings

Is there a way to make the (erase, amplify, clone, ect, easier to see. I have experimented with all spectral layers display settings and colors and it i very difficult to see especially in songs with dense low frequencies. Can the outline be made brighter or thicker? See screenshot of the ‘Erase’ tool

I’ve never found a way to do it, either in SL7 or SL8.

@rraud Yes you can change the Drawing Color parameter in Preferences > Interface.

Thanks Robin, that helps some. A thickness parameter would be nice.
As I stated this is only an annoyance when spectral editing dense low frequency content. It may not be an issue for folks with perfect (or better) vision either.
