I leave the details to developers, but IMO The concept of "always on"
is wrong. In addition I fear that code that tries to "autodetect when
to use, when not to use" is doomed to fail -- It can't know the users
environment ever well enough.

>From SW development standpoint wouldn't it be clear if users just add
option:

   --progressbar

or multiple of other options:

   --use-fancy-colors
   --gimme-round-boxes
   --I-want-bells-and-whistled
   --hey-man-I-got-P4-2800Ghz-gimme-all-you-got

to satisfy what each of one wants :-)

Yay,
