The SuperView uses window priority levels to determine which of several
overlapping windows are visible. You can change the priority levels of
windows so that different ones come into the foreground and others move to the
background.

FIGURE 6.
Window Priority—Window 2 has Higher Priority
When windows overlap, their relative visibility depends on their respective
user-assigned priority levels (see Figure 6). The available levels are one through
six for a six-window system; up to twelve for a twelve-window system, where
one represents the highest priority. The window with the highest priority is the
one that is displayed on top; windows with lower priorities are stacked beneath
it. However, keep in mind that only the overlapped region of a window is
actually obscured by a higher priority window.

No two windows may have the same priority level. If, for example, one
window’s priority is increased, the window previously holding that priority is
decreased one priority level. Promoting (or demoting) one window leaves the
priorities of the other windows unchanged relative to each other.
