When opening the schematic editor for the first time, my eyes were drawn to the
ERC panel on the right which lists various errors and warnings. I like the intent
but I think its presentation is premature, the user is desensitized by the time
actual issues appear. I would suggest hiding that panel until one or more issues are
actually present and then only show the group headings of the ones that have issues.
For example, show the initial Circuit Warnings entry "Unused net class’ and hide the other empty headings.
