Let's put it this way: in rare cases, someone needs to list all installed packages and listing all of them might be actually very slow, especially when we use many remote repositories.
On the other hand, you are actually asking for another feature: Listing ALL INSTALLED packages to remove some of them.
Not really. Yast package manager lists all packages, including installed ones. Sorting by install status gets me list of all installed packages.
Taking a long time to list anything is also not a problem. The problem is that changing any status of any of the item results in things stalling. So the interface is not interactive.
Our proposal for a workaround: Do not install those that you don't want.
That's a poor workaround. Another would be to just re-install the system?
Somehow this works just fine in Aptitude on Debian with even more packages than Leap. But it doesn't work with Yast2 Qt GUI *or* console text UI.
