It'd be awesome if it had an option to:
* automatically install everything suitable found,
* allow you to manually select each item found.

It might be best if this was broken up by type, e.g.:

Please decide how this installation should proceed:
* Modules
  o Completely automatic, everything suitable will be imported
  o Manual selection, you decide exactly what to load
* Content types
  o Completely automatic, everything suitable will be imported
  o Manual selection, you decide exactly what to load
* Views
