The top rows of Story Maps are very important. Knowing which Activity and Task is represented in each column is crucial. If I create a lot of releases eventually the top two rows of cards move off screen. Then I need to keep the individual columns in my mind or constantly move back and forth or zoom. Same with a map that has a lot of Activities and Tasks eventually the Swimlane/Release name move off screen. It would be great if both the Activities and Tasks as well as the Release Name could follow the view if the user zooms in or scrolls them off screen. Could be a configurable feature per story map or automatic.
This would make navigating Story Maps a lot easier, this could even be combined with collapsible Activties and Releases to make Story Maps truly amazing.
