plan: b, t and C open their own view alone or beside what is there, q closes one view

S still puts the board, the agenda and the calendar on the plan screen.
From the documents, b, t or C opens the plan with only that view; on the
plan they add the view beside the others, or focus it if it is there.
q and Esc close the focused view the way they close a document's tile,
back along the trail, and only closing the last view leaves the plan.
