my mockup still has a section for frequently used but only on the front page of the dash and i noted that it was meant to exclude any item on the launcher or the "bookmarked" section i also had in my mockup's front page. �the bookmarked section was for easy access to sometimes used but maybe not frequent apps a person doesn't use enough to want on their launcher but would still like more readily available for them when they do want it. bookmarked section would also be useful for people who don't like launchers.
since the frequently used section would have much greater possibility for change if it excluded things on the launcher and bookmarked section i think it would be more useful and helpful than the current frequent apps sections.
outside of the front page there was no "frequently used" section and also the "available for download section was replaced by a single button located at the bottom of the dash.
not everyone likes having the apps and files&folders on the launcher and some people don't even like launchers in general. �i personally like the launcher but would disable the apps and files lenses on it if i were to use Unity instead of Gnome2 as my usual desktop environment. �i still use unity every now and then but as i said i don't find it enjoyable.
