The Clarett 8Pre layout was very wide; it would be preferable if the
main window output controls were placed below the global & input
controls like for the Gen 3 18i8 and 18i20.
Rather than use the presence of speaker switching to determine which
main window layout to use, check the number of input & output
controls, and use the taller layout if the total is 12 or more.
The Clarett+ series don't have a pad function, so can't rely on that
for creating input controls. Look for "Line ... Capture Switch" rather
than "Line ... Pad Capture Switch".
