When I started this project I hadn't thought about a touchscreen yet. Actually, this was also a trial and I had the monitor left. I have now discovered that I miss a few buttons with some layouts, or that the description of the buttons is not quite correct. So if I'm going to make a version 2.0 again, I will definitely consider a touchscreen. But I think real buttons are part of it. I also found out that I may have made the case a bit too small, as I now have little room for a hopper. But I'm just going to try.
