also since cameras have limited amount of buttons
if they were allowed to do more
do you
esp if since you already paid for camera..
some features that older/newer/other cameras don't have (or competitor brands even.)
e.g. dim/brighten the LCD monitor according to surrounding lighting
(would require REC mode or if play mode save from last time?)
if e.g. in videos for newer cameras the zoom is very slow(but for pics has fast, different even though not vari-zoom-control speed model) (maybe if makes for pro-look)
but zoom-out is too slow may miss sudden moving events
so if options for zoom-in-out so
after delay instead increases zoom-in-out speed to max
if had to press many buttons to do one thing might be clumsy
it the presses/hold/multi/combos were customizable so it would be different
depending on what you want
if for those special keys ui feedback would probably help
if CHDK menu items if you pres and hold down (after initial press) nothing happens
apparently development also is fragmented (many different models)
and there are priority issues maybe a way to triage/rate things?
