And that _used_ to be anaconda's UI and anaconda used the group tag.
That was changed so that:
a) the grouping information could be changed by third parties without
requiring the packages to be rebuilt
b) browsing through every package in the distribution wasn't

While a good high level description of what's wanted, it's not a very
good place to start for designing a UI. Things really need to be far
more focused. Use cases are one common approach; there are others.

This is actually a direction that we (pnasrat, clumens, myself and a few
others) were looking at when we got to the current package selection UI.
The problems started coming in around how to sanely handle a native UI
where you want to allow multiple selection of packages, and then viewing
even more details without too many levels of nested dialogs.

Search is *definitely* something that's incredibly useful and important.
Realistically, it's probably more interesting than browse for most use
cases. Can the search that's currently there be improved, yep. Was
easiest to just start with 'yum search' and then improve from there.
