The list of personal and shared segments in SiteCatalyst 15 and Report Builder are incredibly lengthy. We've asked all our Discover users to unshare all their segments to help make the list more manageable.
It'd be great if the drop-down box only showed the list of Segment Folders. Then hovering over the folder name would display the segments in that folder. The list would be so much shorter and concise, making it much easier to use!
Then lather, rinse and repeat in Report Builder.
