The "live" tool its a nice feature, but Ill not miss it if instead of real time computation I could have more setting for each component. I know that complexity will rise, but without some parameters my simulation loses reliability... If adding options could make the app too heavy for iPads computational engine, it comes necessary to release some documentation on which parameters are given as default and which values do they have. A good spice simulator in Google play is EveryCircuit, has a lot less components but provided with more customization. Anyway, you did a good job, dont stop working on it!
