I use the combo of Trello and Stories on Board in a project management setting. Trello is the source for tasks, activities and collaboration while Stories on Board gives me the overall workflow (horizontal). The ability to have releases/phases (vertically) is a feature of Stories on Board that is GREAT. For me however typically the phases are built on separate trello boards as they involve different teams. So having the ability to sync to one overall story map from the different phases would make Stories on Board a MUST have!!
