Default Window and Pane Sizes under MacOS

[iaw4]

SH3D always seems to like to spread the full monitor left to right, and make my panes on the left side too small. the last pane size doesn't seem to be kept in the sh3d file.

can the default be changed?

On my PC, on a 4K monitor, it runs in a window, not full screen by default. The icon size is fine by default.

on my macos 6K DELL monitor, it runs in a window, too, but the window extends too far left and right, covering everything else. if I designed a railroad car, it would be perfect. in fairness, if I had to choose one layout, the current default is as good as any for as many monitors as possible. however, it would be nice to be able to tailor it towards projects or at least preferences.
