Hey Sebastian,
I played this simulation for hours, but there were some things you could maybe add in your next update.
Zooming in and out of the workspace would be really cool so we can make bigger and more complex chips. I know this is already possible by pressing ctrl&-, but the hitboxes don't match up which makes it basically useless.
I did see that you are creating a system for editing existing chips, Great with a capital G!
Being able to see the decimal count of a eight-bit number would be cool. Could be implemented like: When creating a new input/output you can choose between a normal in/out, a four-bit in/out, eight-bit and some custom number bits. Might need to make an option to enable/disable two's compliment though.
I think that by adding a edit button my next idea is less useful, i'll still mention it though: multiple tabs which you can work in. I don't know what to do about chips being inside other chips that are being worked on though, and like I said, this feature is not necessary.
I enjoyed your simulation a lot and wish you the best of luck with the new update, I know how stressful it can be to have announced a new update but still having to make a part of it, so take your time (but be quick if you know what I mean :P).
