Add, delete and reorder a band. Those three were reached from a bar painted onto
the page until the overlays went, and have had no door since.
Shown when nothing inside the page is selected — after the band and the block,
because those are things you opened deliberately and this is what is there when
you have not.
The nav lists the same bands and is for GOING somewhere; this is for changing what
the page is made of. Two verbs on the same nouns, and mixing them would mean a nav
row that sometimes navigates and sometimes deletes.
Same reorder gesture as pages, gallery items and partners.
