The four mode buttons become one switch, Slide | A | B | Erase, whose
marker slides to the choice. In Erase the brush's two jobs and the
picture on top are switches of the same kind, and PSD is a plain
off | on.
Save moves to the bottom right of the node, larger, with a disk icon,
in a row of its own with the name of the files and the PSD choice.
The files can be named. A Name field on the node takes letters,
digits, spaces, dots, dashes and underscores; the server checks the
same rule and refuses anything else, so a folder is never part of a
name. A new optional filename input takes a wired name, such as the
source picture's file name: its folder and extension are dropped. The
save route still names no file to read.
Size and Soft scrub from their label and from the unit inside the box
as well as from the number (the scrub control gains handle() for this).
Workflows saved before load as they were: 60 that use the node were
opened (the pack's examples, published workflows, the oldest saved
shapes), 72 nodes kept their size, mode and links. The node is one
input socket taller.
