Since releases can have status and workflow, it would be great to have a list view. It would be similar to the list view for features and ideas : customizable field list, customizable filters, and bookmarkable - also able to be included in notebooks.
It would be nice to run a few list reports across multiple products.
This can be achieved through Aha! Reports. Please see details here: http://support.aha.io/hc/en-us/articles/205649325-Create-a-list-table
