Amix now supports multiple screens, although it's a far cry from
graphics.library/intuition (for example, screens can not be dragged).  Any
graphics modes can be used, and the standard console device supports the
A2024 in 1024x800 pixel mode.  Unfortunately, the windowing system doesn't
support anything other than 640x200, although that will hopefully change
soon.  The windowing system might not ever support the A2024 hires mode,
though, because it's just too bizarre.  The windowing system normally
uses 3 bitplanes, but most of the colors are for "dropshadows", borders,
background, etc.; the actual data area of the window is only one bitplane.

The main objectives of supporting multiple screens include allowing
multiple windowing systems and mutiple virtual terminals.
