If the task pane is open, it should not close when switching views within a project.
For example, when in list view, open a task. Then click “Board” and the task pane hides.
The UI should keep the specific task open when switching between List, Board, Timeline, or Calendar views.
Why? For me, a scenario is to view a task from the Inbox and want to drilldown to the task in Timeline view. I do this by clicking the task’s project, which moves to the project’s default view, which is often List. (As an aside, the task pane does stay open between Inbox and List view.) And then I click Timeline and lose the task I wanted to drilldown on.
