In the long run, I think it would be nice to have sections without page names as well.
Another thing, that would make the Parameter COMP even more useful, would be the possibility to combine parameters from different COMPs. We could built unified UI's very fast.
In terms of different operators, you could use one parameter COMP per operator, then combine them in a container, aligning children Top to Bottom for example. Would that help? Cheers, Rob.
