This is probably 7.1 material.

When you perform an upgrade the installer asks if you want to install
additional packages.  I suggest that there be an option to choose from
bigger categories too ('Development') etc.  This way you could
change/expand easily what the workstation is used for without a need to
know which specific packages are in there.  

Also, this could be used to create systems that are guarenteed to have at
least all the packages that a fresh install would.
