Add a "memo" or "notes" flag.

[Firstyear]

Addition of a flag such as --notes or --memo to allow a user to add custom notes and text during a package install. An example invocation would be:

zypper install openssl --notes "for managing certs"

These notes could then be viewed with zypper info packagename.

Sometimes when installing a package, it can be useful to remember why you installed it or take other notes.

Well, you can add --userdata to commands remembered in the /var/log/zypp/history (package and repo actions).
By now zypper does not refer to the history, but it would at least be anchored in your system.

$ zypper --userdata 'demo it' up ImageMagick
...
$ grep ImageMagick /var/log/zypp/history
...

That's not a very good user experience though is it.

I think as much of this is about having a good, visible ux so that people can use the feature effectively.
