Okay, My suggestions:

1. Enable the spice simulator by default and start shipping it with windows
nightlies. This way we will find much more bugs. Because I doubt everyone
is running with the simulator on even on nightlies. Same goes for the OCE
and step stuff. This I see as a must to get a smoother v5 transition for
most users, even those moving from v4 stable to v5 stable without ever
trying nightlies.


Everything should be enabled for the windows nightlies. It has been when
the OCE stuff and ngspice stuff was merged. If it not it is a bug.


2. Parse the "value" field and reference in the simulator to get the basic
primitives. like Resistor and Capactiors, inductors etc, based on the first
Letter in the Reference. We already have name-dependent functions for the
differential-pair so having this here, and

3. Move the Spice_Netlist_Enabled field to a new right-side toggle menu to
select between "Spice and PCB, Spice Only, PCB only", so one can specify if
the item should be added to both the PCB and the Spice netlist, or only one
of them, by default I guess both should be enabled.

4. When the Spice_Model field is selected, the button "Edit Spice Model"
should be shown under there, instead of always on the left side. Just to be
more like the other fields.

5. Add context-menu entries and toolbar buttons for the simulator interface.

This would make the simulator seem like its a part of kicad and not only a
strange addon that is just hackishly attached to kicad with duct-tape. Dont
get me wrong, Its an awesome feature, and works well it just looks like an
outsider when using it currently.



As for the polishing up before the V5, there's several tasks to do:
