Sorry if this ought to be a feature request; just checking.
A single left-click is all that’s necessary to “turn on” any footnote in the inspector. But to get into that footnote for actual editing seems to take a whole lot more clicks, and I have a hard time getting the timing right to activate it.
Does the configuration provide any settings or adjustments? It seems that once you have “turned on” a note, you should be able to enter edit mode with a single click.
