Currently, you only get the "release" button on the done column of a Kanban board.

In Scrum, you get to plan your versions better (across multiple sprints). But there is no "release" button on each version. It seems the only way to release a version is to do it from the "Manage Versions" page.

From a Scrum board, it takes multiple clicks to get to the "Manage Versions" page - and it's not clearly signposted that you need to / how to get there.

This seems stupid. You can create versions, and edit version details from the plan mode of a Scrum board.

You should at least be able to get to the "Manage Versions" page with one click from the Versions panel on the the Scrum board, or release a version directly from the board.
