here my quick finding after testing a few of your bug list...
1) FIXED (large font setting is retained after reboot)
2) i dont understand what the statement wants. deselecting the checkbos will hide the measurement, probably that what it does.
3) FIXED. FFT works on other channels even if CH1 is off
4) if they fixed this, someone will mourn, measurement got covered by math function, if they move the label to top, someone may mourn the signal got covered, so its hard to satisfy everybody, imho.
5) probably hardware limitation on some unit, i dont experience this. easy workaround... shift the vertical offset until signal is at 0.
6) probably hardware or software limitation. saving bigger file regardless of format, took long time. what do you expect on a $399 scope?
7) havent tried
not fixed.
9) FIXED. see attached
.... not tried
13) i successfully downloaded nongarbage 24M yesterday...
so you see most bugs reported here are fixed, or at least i've not experience them so far...
