Hi, first I want to say that excellent work and congratulate you for carrying out this application. I discovered it now when I started my internship in electronic engineering and I found it excellent.
Regarding my proposal, I would like to be able to manipulate the oscilloscope in a more "realistic" way in the future, and also (if it can be added) the waveform generator. It would simulate better what it is like to work in a laboratory and would add that "plus" for people to interact and learn how to use it.
I know it must be difficult to implement it but it's something that occurred to me while I was using it.
I want to say that I see a lot of future for teaching, if the pandemic had continued until today I am sure that it would have been used in universities.
