Please consider the following.\r\n>\r\n> 1. A `View` menu with a hide/show switch for the Graphics Window. (Some `Tools`, such as Hiding/showing the Command Center, could be moved there as well.)\r\n>\r\n> 2. A Boolean primitive to accomplish this (e.g., `display-graphics-window`). This should be usable in the `startup` procedure.\r\n>\r\n> More radically, since some models do not need a graphics window, one might introduce a Boolean primitive to allow disabling its creation (in the startup procedure)."}}
