	if (match.child_count > 0 && this.config.showPopoverOnMatchLabelClick) {
	this.clearPreviousPopoverSelections();
	opponents.classList.add('popover-selected');
	this.showPopover(match);
	}

I added a popover on click in the past, but it's not nice to use. Instead a rich tooltip should show after a delay, or something like that.
