Am I supposed to read all this ? I need to list only installed items so that I do not waste hours for reading the items which are not installed.

When the list of non-installed items overflows the limits of my Command Prompt, what will I do ?
List pages and pages and pages ? Hm... No. This is not convenient.

We need a list mode which shows only installed items.
