In the screen asking how to resolve missing dependencies, the choosen option applies to *all* packages. But often there are packages which are really needed (so missing packages must be installed) and such which are not necessarily but require a lot of other packages (e.g. in a non-KDE environment a package linked against kde-libs requires the whole KDE base and libs packages). It would be usefully if the user can decide how the dependencies for a *single* package shall be resolved. So the lower three radiobuttons (install all packages, no packages or ignore deps) should be linked against one entry in the missing dependency list and not affecting all. When enabling multi-selection in the list the current behavior can be kept by marking all entries when entering the screen.
Looks very similar to bug 8595. *** This bug has been marked as a duplicate of 8495 ***
