packages-to-remove dialog should allow user to toggle exceptions

[Christoph Buchner]

I think this is the right package to report this feature request against. I also searched update-manager bugs but couldn't find a duplicate.

On upgrading Ubuntu, after the new packages have been installed and configured, the user is presented with a dialog offering a (typically great) number of "old/obsolete" packages, and the only options are to either "Keep" or "Remove" them all.

Normally, it's a good idea to remove the old packages. In the case that the user wants to remove all of them except one, because whatever algorithm is behind this has a false positive, or for some other reason, this is not possible - it's either keep them all, or remove them all. It would be great if the list of packages had checkboxes where you could exempt certain packages from being kept/removed.

(In my case, on upgrading from Precise to Quantal, I would have liked to keep a self-installed package of an old/unmaintained application - bouml - that the release-upgrader wanted to remove.)
