This both disagrees and agrees with traditional wisdom.
Traditional wisdom asks for an animated progress indicator to
improve software responsiveness while a simple busy indicator may
be more energy-efficient. Traditional wisdom also asks for
consistent menus which keep useless menu items on the menu window,
but deactivate them, in order to improve user
friendliness  (p. ). However, such items
may be removed to save energy once a user has become familiar with
the software. To summarize, features that do not accelerate usage
should be avoided. This does agree with traditional wisdom on task
queue optimization for ignoring outdated user
requests  (p. ).
