It seems that it limits the maximum data points to 3072. It's a PC with basically unlimited resources. Why is there such a limit?
Currently this is due to the way some algorithms (e.g. histograms) and display (e.g. OpenGL buffer size) are implemented. This limit can be drastically improved (to the ~million scale); it's just a matter of priority, and putting the work in. We can have it in by next update if you find it important.
Color grading would be much better. The worse thing about intensity grading is that you are typically interested in the parts of the signal which occur the least. At low (or near zero) intensity, that information is not visible. Some oscilloscopes (like the ones from R&S) even have reverse intensity grading which highlights the rarely occuring waveforms.
Color grading would be nice. Of course, a lot of features, like changing the horizontal axis from time to distance would also be nice to have. The attached screen shot was taken from the following PicoTech 9400 sampling scope training class:

Note the several display styles they offer, Dots, Vectors, Variable Persistence..... I don't think anyone would suggest the software is polished. However, I thought based on the following that they felt it was good enough and to drive the stake into the ground and move ahead. Which is what I did.
Using the power user mode to zoom in as much as possible and using the Light Mode and disabling vector trace mode for all channels. This is about the best contrast I can get.
Here is a prerelease version that significantly increases the range of the brightness slider, and adds color-grading:

When using very high intensity settings, there may be speckles within the open eye due to statistical noise in the CDF samples. These will reduce as the minimum number of triggers per CDF sample (Section 3.7.1) is increased.
Note that we are nominally out of office this weekend. But this was a small enough change, and is holding up the review.
You should review the product as it exists now.
For now, I will hold off with the review until they decide what they want to do.
We stand by this statement for 99% of the review - the product will continue to improve for the foreseeable future, and so any review must necessarily be a snapshot.
We singled out the eye diagram issue since it's one of the main target applications (signal integrity), and is being held up by a UI limitation. The cost-benefit tradeoff makes this point a bit silly not to address.
Overall, we found the review fair and very thorough. If the UI patch resolves the issue, we're happy for it to be published.
