The first thing I would love is to somehow rotate the chips around. If possible I would really like if you could zoom out of the workspace to make it bigger and would it be possible to make a mobile app? It would be great that I could work on my calculator anywhere from my phone. Also a game-changer would be so you could share a circuit based on a file that you could send for example. Some more displays would be nice too, and the integration like in the videos that you could have the decoder directly in the display. I absolutely love this program though, and spent about 6hours at it (I have it for two days now) and made a simple 4 bit calculator with a memory.

I required a bit more space for my 8-bit computer, so i modded the game to make zooming in and out possible. All the other features, except for rotating, are in the game already. 

I think being able to rotate the chips would be cool. At the moment I'd rather have bundled cables though (8 or 16 bit cables for example)
