Is it possible to group graphical objects in OMEdit into something like subsystems? Currently it appears that OMEdit only allows for one large "flat" design, right? However, A little bit more complex models can then hardly fit into the "canvas".

But I confess that being a complete newbie into (Open)Modelica, I cannot see what programming step would correspond to such graphical grouping.

Is it possible to flip graphical objects horizontally or vertically in the graphical editor OMEdit?
