@User As your work on the waveform viewer progresses nicely, may I bug you with another feature idea? I always struggle with the

spice

syntax for the simulations, so I always need the manual at hand. How about a GUI (nothing fancy) to setup the simulations? As there is not much a vanilla

spice

can do this should not be too much effort, I hope. Just reading the corresponding entries from the schematic (if already existing), allowing to modify in the GUI (switching sims on/off, setting params), and when done write back.
