Anatomy of Planner
The Planner screen has three regions.
1. The left pane contains three collapsible sections:
a. Sprints has lower- level sub-releases with a bigger indentation to visually indicate their place in the release tree. Only the release and sprint of the current scope, its children, and the backlogs (if applicable) are visible here.
b. List of teams, participating in the release or its sprints.
c. List of project members, assigned to at least one work item in the release or sprint.
d. Relations can be used to optionally categorize work items by requirements and user stories and use custom colors to make them visually easier to distinguish on the interface.
2. The center pane contains a filtered, orderable list of work items with their most important properties displayed: priority, key, type, summary, Story Points (if enabled), assignees, teams and release targets.
3. The right pane contains a view feature to see more details about a selected item without fully opening it. This information is broken into four sections, all of which are collapsible for convenience:
a. Details
b. Description
c. Relations
d. Comments
Above these panes, is the action bar which is useful if you want to toggle the left or right panes or create a new item or a new (sub)release. The quick icons above both the left and the right panes are useful if you want to toggle their corresponding sections.
