interim versions that eliminate the stuttering when
scrolling to view parts of the drawdown that lie

button in the slider. The disadvantage is that sliders
do not respond to swiping the trackpad or stroking the
surface of a magic mouse.

to Save files back into the package. The zip
packages expand into a normal folder when the downloaded
icon is double clicked.

||Big Sur introduced a new fast scrolling
method; unfortunately it wants to scroll the entire window
contents whereas Fiberworks wants to keep the threading,
treadling and tieup in place, so Big Sur and Fiberworks are
in a fight over what to do. There are several ways to
