It's not entirely what Dave is suggesting.He's suggesting the split button dropdown should have a checkmark to set the default behaviour of the button.
@Dave Page In that case it will contradict with Save and Save As. Save As here is an extension of the menu and not the behavioural option.
I don't think it contradicts. Open vs. Open In new Tab is, for the most part, a choice that most users will generally build into their workflow, whereas Save vs. Save As choices will more commonly depend on the situation I believe.
In other words, I'm more likely to select the Open behaviour I prefer, and use it all the time, but the Save behaviour is dependent on what I'm doing at the time.
