UPDATE - THIS PACKAGE HAS BEEN REMOVED FROM INTREPID
IT WAS IN THE BETA VERSION ONLY.
I found the "cruft remover app" today which is new to Ubuntu with the intrepid release.
A neat app if used properly, but will need to gather more information about the packages on a system and the frequency of use etc.. to give the user more info before prompting for removal of a package.
I think the default for most check boxes until that point is reached should be False.
anyway.. this blog sums up the app much better than I could
By the way "cruft"? I bet that wasn't the original name of this app.
