I searched the configuration menus, manual and tried some combinations but there doesn't seem to be a quick zoom & pan with mouse wheel feature in Picoscope 6. It's a bit annoying to click the small toolbar button, select a rectangular area and then adjust the area in zoom overview window. It's especially annyoing that there isn't horizontal zoom button because the general zoom applies to voltage axis and the 8-bit samples turn to ugly "stairs". 99% of time i'd like to zoom in on time axis only and leave the amplitude as it is.
Many application have buttons like this, maybe you can add these keys to Picoscope also:
Ctrl + Wheel = Horizontal Zoom
Wheel = Horizontal pan
Some applications handle mouse wheel differently depending on the cursor position. E.g. when cursor is on time axis the scrolling pans time, when cursors is on voltage axis, scrolling offsets channel. Cursors should also change when it's on active area.
Actually, when i already started complaining, then channel offsetting is also bit clumsy. If scale is let's say 0-5V then offset adjustment should step on 0.5V, 1V, 1.5V... or 0.1V, 0.2V, 0.3V.... Today offset changes by milli/micro volts and it's quite hard to lock it to the position where it displays nice rounded numbers. This applies to time axis also.
One thing more: would be nice to put text labels on channels - then waveforms can be understood later when copy-pasting the images to report file.
Otherwise I'm very happy with PicoScope
