Thanks for the feedback. As this is based on forum feedback however, credit is all yours.
You can keep this as a preference for any configuration, but it will only have an effect on displayed output when there are more samples per div in the buffer than needed for the display (i.e. > 25 samples per div). This is the case with fast mode (250 samples per div) or if zooming out (increase T/Div) on a stopped waveform when in normal mode.
There is hysteresis on all auto-fit dimensions already, but I’ll see if I can reproduce it and tune it a bit to avoid this issue.
