Once an Idea is promoted to a Feature, there is only limited integration between that Feature and Idea. I can understand why you would not want modifications to a Feature name or description to update that information automatically in the related Idea, and vice versa. But maybe having an Action to be able to do this, would be good.
And currently, the only Status that is updated automatically is when the Feature status is changed to Released, it updates the Idea status to Implemented. It would be nice for this to be configurable, and have other levels of Feature statuses tied to Idea statuses
