I want to start by stating that I think this is a super cool software and I am excited to dig even deeper. Ultimately I could see this being used as really powerful circuit design software and I would love to use it instructionally in the Electronic classes that I teach at the high school level. I build a 2 LED flasher using the 555 timer and the circuit did not oscillate as intended. I triple and quadruple checked my schematic to make sure that I was not missing any connections but the 555 timer does not seem to be functioning properly. Happy to provide a link and a picture of the schematic in a Google drive folder if a dev is interested in checking it out.
