Search-hit safety indicators needed in SafeZone

I’m used to the SafeWeb feature of Norton products, in which green, gray, and red symbols provide some indication of search-result safety. SafeZone has no such symbols, and I feel less secure when browsing. If a browser hit corresponds to a site that hosts malware or other threats, I want to know it.

Apparently add-ons/plug-ins exist that provide evaluations of search-result safety, similar to Norton SafeWeb. (I think such indications may be based on some type of Google site-analysis database.) Is there any way to install a non-Avast add-on like that in SafeZone? Or might Avast (if anyone from Avast is reading this) consider providing such a feature in the near future?
