Say you install app A through Cydia. App A requires dependancies B and C so Cydia also installs those packages. Now I don't like the app, have problems with the app, or just move on. I go to remove app A though Cydia but Cydia only offers to remove app A leaving B and C in the system even if they aren't used by anything else. I could go to Expert in my list of installed packages but what if I don't remember that packages B and C were related to A? Maybe this doesn't bother others but it bothers me that stuff is getting littered around on the phone. Is there a way to tell Cydia to do a full uninstall of dependancies if none of the other installed programs claim that package as a dependency? In Linux I know you can have it do that with .deb packages.
