May I please make some feature suggestions?

- Make the signal viewer able to run the synthesizer... that is
although you wouldn't want ivi to be embedded into your viewer, make
the viewer able to run various simulators in a way that appears
seamlessly integrated to the user.

- Allow the user to "rerun" the simulation without changing the signal
view.  Say I'm looking through the results of the simulation and find
a subtle bug.  What I'd really like to do is edit the RTL and rerun
it, putting me right back where I was so I can continue looking for
other bugs.

There are certain things that, for instance, ModelSim does that I
wouldn't ask for.  Actually, I hate ModelSim.  But one thing it can do
is allow you to simulate for some period, and that appears in the wave
viewer.  Then you can simulate some more, etc.  Don't bother trying to
do that.  If the second suggestion requires a complete rerun of the
simulation, fine... just give me the same signals, zoom ratio, view
offset, and selection.

Thank you for working on a better viewer.
