Had a few questions about working in next-gen projects I was hoping someone could answer.
1. When will sub-tasks be supported? I know this is logged in the 'coming soon' section of the JIRA roadmap, but does anyone have some experience in how quickly these deliverables ship?
2. Is there any interface to view issues which have been completed in prior sprints? One we complete a sprint any issues which were considered 'done' seem to go away entirely.
3. Is there a way to create new custom-field types for issues? For instance, a multi-line field? There seems to be a very limited selection of custom field types to add to issues in the Issue Type configuration.
