Is it just me, or can you only set up one workflow per organization? Does that mean that you can't have multiple teams/projects using their own styles within one account?
Some of our users have extra steps in their workflow (for example, "waiting for app store review") that some of the project teams hide in their workspace (each column in the workflow can be hidden by an individual user).
In the future we might support different "departments" within an organization to allow for multiple ways of working, but it's not at the top of the list of things to do currently.
We have some of the building blocks in place for bigger teams, but it's not a priority right now.
