Control if nested properties to are collapsed by default

I’m seeing that nested component properties are now collapsed by default and there’s no way to control this. This makes these properties harder to discover for the designers using my system. I understand some people want them collapsed by default and so that change was made in UI3. I need an option to control if the nested properties are expanded or not.

I’d prefer actually to be able to order these nested properties in with the parent component properties instead of separating them altogether. It doesn’t typically matter to my consuming designer if something is nested or not, they just want to use the parent component.
