Maropost used to be smart and know what folder you were looking at last. Then when you created a segment, it started putting the segment into your current folder and it kept your view as the current folder. Now when you are in a segment folder and create a segment (or copy one), it puts the new segment where it's supposed to be, but it drops you back up to the top level folder - making you drill back down to find the segment you just created.
This should be an easy fix. It feels like the whole UI has gone backwards. So much lost functionality.
