Because I manage physical product development, releases are longer and there are a lot more epics in each. It's not remotely useful to display 89 features in one column for the only release in a given product. If I could break up the features board by release phase instead of release, I'd actually be able to use it as intended. I initially considered labeling release phases as releases for this reason but the visualization doesn't make sense.
Its currently possible to create tables on the Features List page which display Release phases as a table column, alongside other core Feature related information. This can be a potential workaround as a place to manage development.
At this time, we do not have plans to display release phases as columns on the feature board due to community feedback and current priorities. However, we hope that the workaround on the Features List page can help.
