I meant waveform viewer mode of the KJWaves itself. A mode in which
only the waveform viewer window is visible. Preferebly, KJWaves could
also accept result or "save" file names as command line arguments.

Well, last time I tried gschem it didn't work for me. It had no
hierarchical circuit support, no ready to use components, no
auto-numbered instances. It was slow to redraw and its wire editing
mode was only slightly better than drawing them in a general purpose
vector graphics editor.

Sorry, I meant "panels" as waveform graphs stacked one over another
(instead of overlaying them as it is now or rendering to a separate
tab) with separately adjusted Y-axis scales. This is a very basic
function of all waveform viewers.

At least all kinds of zooming and panning. Preferably with a zoom
stack as well (so you can return to the previous zoom settings). In
general, there are never too many keyboard shortcuts.

Other tools usually have two cursors activated with a left and middle
mouse button.

Everything. ;-) Ideally I could start KJWaves with a "save" file name
as an argument and it would restore the view of all waveforms just as
they were when I saved them.

That's very important functionality. Simple arithmetic functions are
good for start but soon you would like to perform more advanced
operations (slicing, eye-diagram, filtering, A2D&D2A conversion). In a
long term an embedded scripting is necessary.

OK, hopefully on Thursday I'll have some time to spend on this.

I see. Nice function in fact. Still, I would rather put this knob in
an annotation tool options dialog.
