I've played this simulation for hours, and here are some features I want you to add.
First, I would like a Transparency feature to see inside chips. Second, I can't possibly get over the frustration of following your video to the last step and realizing that I messed up on the chip design for the previous chip so I have to start over again. So, I would like an Edit Chip feature that lets you select a chip then press EDIT and be able to edit the chip. Third, because of the previous issue, my projects tab is quite big. Therefore, I would like a Delete Project feature. That's about it! I hope to see the new version soon!
