In PMMv1, if you were on the QAN page, you could quickly navigate back to 'MySQL Overview' of the same server you are examining in the QAN by just 1 click under the "--- MySQL" menu in the upper right.
Now in PMMv2, you must always click 1 extra menu '--- Services
> MySQL Services' and from here, you can click '-- MySQL -> MySQL Overview' and then you must re-select the "Service" (huh? service? why not hostname?) that you want to view.
Why the extra click? Why can't the "entire menu" be displayed on the QAN pages?
Navigational complexity has certainly increased in PMMv2 over the simplicity of PMMv1.
