A space-saving redesign plus more megapixels for the Sit/Stand/Walk Desk

I rebuilt the Sit/Stand/Walk desk from an A-frame to a foot-deep rectangle so that it takes up a few feet less space back-to-front.  I also replaced the main 30" monitors with slightly smaller 4K monitors.  I have mounts for the laptop and phone but haven’t figured out a good place to put them, since the sliding up and down of the main monitors really takes up a lot of space.  The only realistic option is knee-level, but then they are useless in Stand/Walk mode.
