Human-friendly error messages

[TheNetworkIsDown]

Today one of our guys left Yast open on a client by mistake. Several actions we tried to carry out on that client failed and we just couldn't figure out why. (hardware refresh, highstate, ...) The error was:

product_|-mgrchannels_install_products_|-mgrchannels_install_products_|-all_installed:
    result: false
    name: mgrchannels_install_products
    changes: {
        }

It would be great if there was a clear error message or at least a hint to a logfile containing such.
