We have 3 separate projects, Customer Feedback, In Development, and Past Releases.
We use Customer Feedback to prioritize our development effort, and we move all the feedback that will be incorporated in the next release cycle into a single column.
We would love to be able to easily move this column from the Customer Feedback project to the In Development project.
Once in In Development we move the tasks through Currently Implementing, Ready to Push to Staging, Ready to Test, and Ready to Release columns.
After a release it would be great to move the Ready to Release column to the Past Releases project, where we then add the release date to the column name so we can track when we released certain features.
The ability to easily move a column from one project to another would clean up our projects, help us stay organized, and save us many hours every week.
