As a PM, I want to be able to see all the features in the user story map all tidied together. Right now if I build a story map before putting them in releases, the features are all spaced out when added to features forcing me to move each feature one by one on the story map in order to see a tidy map. This is not only painful but very time consuming ...
The relationship between Epics, Releases and Users Stories is currently very rigid. Epics are defined as large bodies of work that logically create something big that may take several releases to create. Aha! falls short and forces you to organize Feature by Epic OR Release. Should be both.
Ideally I model my User Stories by Epic. Then organize features of users stories into releases. I should end up with both Epic View and Releases View, both with the same Features shown in them.
