Thanks.

I just posted another example - with an idea of how buses "might" be
represented. (This takes buses further than their current, graphical
existence)

Like a filter, or a search. This is possible.

I'm not sure exactly what you mean by this, but if it is along the lines
of searching for a "resistor" connected to "this object", that could be
useful. I'm not sure how the user would specify the search though.

It gets difficult to solve all cases. Grouping by component, e.g.
collecting all components using "resistor-2.sym", or "capacitor-1.sym",
could be a start.

I'm not sure about automatically grouping things by "part number", or
"value". Grouping "could" be customisable by plug-in, but it would be
much more complex to implement.

Turn off what- the grouping?

The 3D-Cad package I occasionally use can expand sub-components. I'm not
sure how well it would work with schematics though - and its certainly
simpler to code without the expansion.


Thanks for the comments,
