Trust me to ask the worng, but obvious question.

The big thing that aptitude does that apt and its friends don't is keep 
track of dependencies between installed packages -- so that wien you 
uninstall a package, other packages that it depends on (and aren't 
needed for another purpose) are automatically uninstalled as well.  It 
has a data base of its own in which it remembers which packages were 
explicitly requested and which are just dependencies.

And the big problem with aptitude is that if you use apt as well as 
aptitude, apt never puts the packages apt installed into its data base 
as being explicitly requested -- so on various occasions it discovers 
they are no longer needed and so proposes to remove them.

Does the Application manager do these things too?
