I agree with Bill and Martyn. PicoScope can be improved significantly, if the scaling is improved.
I have written about it before on this forum. The readability of the scales would increase significantly, if you put an effort into it. To me it is not so important if it is 1 2 5 scaling, and/or pan and scroll.
It seems like relatively simple feature, that will have a big payback on all scopes, from the smallest to the biggest.
