Right click on a symbol, select "go inside", and another drawing
opens up showing what's inside. gschem also should act this
way.
I think what you want is by default for each cell to be an entity that
you can grab and move around. The ability to visually toggle all
hierarchical instances between the contents and a box is fairly useful.
If you want to edit the contents, you have to descend into the block
to edit it. You almost certainly want a mode where when you descend you
only see that block in its zero rotation as well as an edit in place
mode where you edit the block while all the rest of the board is
visible. I'm saying this based on having done quite a bit of
hierarchical layout in the ic world. Haven't done it in the board world
although I've wished for it a few times.
