I wonder if some thought is being given to those using with a laptop and touchpad. It's fairly difficult to expand/shrink the waterfall this way. I understand it may be easier with a mouse wheel. Not really ant better with a touchscreen display. Kludgy at best. Unless there is a current provision for this that I'm not aware of.
For instance, just trying to zoom in/out to the most active SSB portion of 10m and I end up over in CB bands.
Maybe some kind of key combination that allows for expand/contract based around a central frequency is what I'm wondering/thinking about.
Also, I know keyboard scrolling was added after a while in the previous release. I really like to use arrow keys to scroll rather than having to find the -/+ Freq. adjust buttons.
