WHen I or someone else shares a report by linking to it, and they use a segment that the recipient does not have, it will simply show "Unknown Segment" in the dropdown menu. Also there is no way for the recipient to see how the segment has been setup, or any way to add this segment to their "segment library". This is really annoying and is such a basic thing. Please add the functionality for the recipent to at least be able to see the name of the segment and/or its rules/content, and givethem the ability to add the segment to their own list of segments.
