Pinning a workspace keeps it at the top of your list — and once pinned, clicking its pin badge opens a small style picker, so a family of related workspaces can share a matching icon and color at a glance.
A single "mark all as read" action clears every workspace's unread indicator in one click, for the mornings you'd rather start clean than click through each one individually.
Nested phase workspaces (see Organizing bigger projects with phases) show up indented beneath their parent automatically, so a big initiative reads as one connected group rather than a scatter of unrelated rows.
