Can you possible add a an option to undo something with either a button or with ctrl-z? I sometimes accidently delete things that I don't mean to, or adding things that I don't want to; and it would make it more efficient if it was implemented.
It would also be useful if it didn't interfere with the key chip somehow.
A second suggestion is that you should be able to have an infinite workspace to make bigger computers with more possible inputs, outputs, and chips. There are too many limitations.
Another suggestion just off the top of my head is that- and maybe this is a little too much to ask for- you could be able to implement a code in like javascript or python in the outputs, so that when the output is enabled, it runs a script that can perform certain actions. Just a thought, though. Probably too much to do.
