.cp-sendsplit, .cp-send--more): it opens the Schedule message menu, and it is disabled whenever send is.
.sb-popover): its quick choices follow the clock, in dealership time, the same every day. Before 8:00 AM the first row is Later today at 9:00 AM; from 8:00 AM it is Later today at 1:00 PM; from noon there is none. Tomorrow at 9:00 AM always follows. Then Monday at 9:00 AM: it reads Next Monday at 9:00 AM on a Monday, and is left out on a Sunday, when tomorrow is that Monday. Custom time is last.
.sb-shdlg-sheet), with its date select and time select, then Schedule Message and Nevermind. The time list is in 30-minute steps, and times are dealership time.

.cp-logrow). Change opens the custom-time sheet.

.sb-sheet), and Custom time uses the wheel (.sb-rolodex).
Engineer note. (1) The edit endpoint must check a new time before Reschedule and Change ship. (2) The mobile long press must not collide with the send button's tooltip.
