We recently modified the Segmentation page to enhance it's capability. Previously, Segmentation was a place to get near real time insights from your data, you were limited to 1 query at a time and also never had access to historical data.
We have now enhanced Segmentation with a "Recent Queries" section, which keep track of multiple queries run by you while also provides you the following capabilities:
- Email you an alert when the segment is computed
- You can re-run an old query again
- You can save any of the recent queries as Custom Segments
- You can view a sample of 50 users any time you want, without running the segment again
- Export (all or selected) User Attributes of the Segment. More details in this post.
