The device list under segments in Experimentation needs a clean up. I know what segments to use when analyzing experimentation results but the list is so long it looks messy and could use renaming or removal of some of them. For example, I still see Desktop (deprecated) it has been there for many years I think we can remove it if no one is using it? The other one is the Phone. We have iPhone, Other Phones and All Phones. I personally don't know what the difference is between Other Phones and All Phones. we can separate them by name like Android, Iphone and All Phones. it just looks confusing. Maybe it needs a better name. Not a priority but definitely a nice clean up would be nice.

I also don't know why the segment by new vs returning visitors was removed. I know we can do this by doing an audience segmentation, but sometimes I have experiments that are for everyone, and then in the report, I'd like to segment by that type of visitor.
