How to present packages (as opposed to end-user applications) in software-center.

The ratio of application vs package is currently 1 to 10, so if we just dump them into the center it will look much like synaptic (just less powerful) for most of the packages shown. Should we even list all non-applications in software-center? Or should we put them in other areas, e.g. Downloads background and font packages under System->Preferences->Appearance->Backgrounds & Fonts

Goal:
 - show all packages

Three overall challenges:

 1. appropriate categorization
  * add top level category for most of these packages
   * what would this category be called?
    * "Tech tools"
    * "Packages" - possibly too attractive for people who don't know what packages are
    * "System Packages"
  * with sub-categories for each ubuntu archive section (we have something like 40)
    * icons for each (eg font icon), generic package icon (different from application without icon)
  * a "Wine" department in the Installed Software section, for installed Windows applications

  * sections
    * should create a transition section in the control file for transitional packages with nothing in them
  * we don't have debtags in the Ubuntu archive!
   * talk to Soyuz team about this
   

 2.  - how/when non-application packages should appear in search results
  * one idea: non-application packages appear further down the results
  * selectable scope for searches (all packages, graphical applications only)
   * what would we call "graphical applications" if the scope is exposed in the interface?
   * "There are no application results, but there are 2 non-application results"...
  * use case: someone searches for a game, its -data package shows up too
  * use case: someone searches for emerillon, gets no results, because emerillon has no .desktop file

 3. how to present individual packages when they do appear
  * Most prominently use their synopsis rather than their name

 4. Other ways to present particular classes of non-application packages
  * Screensavers in the Screensaver Preferences
  * Fonts in ... we have no Fonts interface at the moment
   * User has to find a way of opening ~/.fonts
   * Font Viewer has an "Install Font" button, but
   * TODO: Investigate font managers and consider installing one of them by default
  * Panel applets in "Add to Panel" dialog

Other suggestions:
 * Have a generic package icon that's distinct from the generic application-without-an-icon icon
 * Specialize the generic icons by type (e.g. fonts) or derive the icon from
   the section

Other issues:

 * How to deal with transitional packages?
  * We don't have a good way of identifying which packages are transitional
   * introduce a separate Section for them
    * TODO Find and sectionize all transitional packages

 * packages you have installed that are not in the archive
  * either no longer in the archive, or installed manually
   * we don't know which, because we don't track origin
    * maybe dpkg could track this? - it would need to know what it was being called from
     * if it came from our archive, but is no longer there, it's probably obsolete
    * attach a URL to every .deb
   * example: old kernel packages
  * you can remove them, but you can't reinstall them
   * maybe warn about this before removing it
 * should search results for "get software" include packages you have that you are to remove?
