Of course, you are 100% right (at least for me and hundreds of my site's members who gave up because of the poor end users ergonomics of Dolphin).

Dolphin script is technically greatly improved, and the admin part too. But, in my humble opinion of course, ergonomics of the navigation is worst than ever (was already not so good in the previous versions) with D7.

D7 is looking great at the first sight... but becomes quickly boring as soon as trying to browse such site.
