IDA-STEP is opening one workbench window for each XIM or STEP file.
Like most other window applications IDA-STEP has a global menu,
toolbar
and a statusbar. Inside the main working area one or several views
can
show up. Each view may have its own individual toolbar. There is a
wide
range of possibilities on how the views can be arranged. A fixed
collection of views at dedicated positions and sizes is called a
perspective.
