### "DeskTop" Application
AUX $8E00-$FFFF (with hole at $C000-$CFFF for I/O and at $ED00-$FAFF for
data buffer) is the DeskTop application itself, with desktop and file
icons, menus, dialogs, and so on.
DeskTop application code is in the lower 48k of both Aux and Main:
* Aux $8E00-$BFFF - sitting above the GUI library
* Main $4000-$BEFF
And in the Aux language card area (accessible from both aux and main code) are relays, buffers and resources:
* Aux $D000-$ECFF - relays and other aux/main helpers, resources (menus, strings, window)
* Aux $ED00-$FAFF - hole for data buffer
* Aux $FB00-$FFFF - more resources (file types, icons)
($C000-$CFFF is reserved for I/O, and main $BF page and language card is ProDOS)
```
