these are canvases (i assume). i use a configurable canvas array
and i create and destroy canvases on demand.
but i create a few panels at startup time which are command frames.
the panels are a bit tedious to build, so building them once
seemed reasonable to me (but i guess reason may not always the best guide).
so the rule seems to me to a bit vague. some questions i have
are: What is a pop-up? Does the size of the application matter?
