@JulianWolf {first, second, third} = someList = functionReturningAList[]

What gives? How do I always (programmatically) show the second-level rows? I know there's a right-click menu option "Show 1 more row at this level" / "Show 5 more rows at this level" but I don't want to click that every time.

Just a quick hint. It's probably in TypeSystem`NestedGrid`PackagePrivate`iDynamicNestedGrid.

@hftf No time to dig more now, but just look at the PrintDefinitionsLocal at that.
