Well that may be the prosumer aspect. The thinking, in building an NLE for “the rest of us” would be, default is easy, and those of us who tend toward pro use can figure out how to turn it off. Whereas Joe Consumer shouldn’t be expected to find and enable all the “easy-auto” functions.
Look at Apple’s dialogue boxes. Out of the box, many apps give you the simple box. Those that know better will click the triangle button and use the full navigation and save as window.
Another analogy is the prosumer video camera. Note the All Auto easy setting. Anyone can turn it on and shoot, auto focus, auto exposure, auto everything. THEN if you are ambitious, try Manual or Aperture preferred, etc.
It seems clear that FCPX will be VERY prosumer friendly out of the box; whether it has real depth, that’s what we’re waiting to learn.
