Why is there no Arrange button on some hubs?
It is offered where there is enough to arrange. On a hub with only two or three entries the control would cost more attention than it saves.
From the guide Arranging Your Tools & Sections.
Where to find it
- On the web: the "Arrange" pill at the end of a hub’s section strip.
- On the iPhone and on Android: "Arrange" at the top of the Tools tab.
