v1.519,520: mobile improvements
v1.519 May 6, 2022
When taping the frequency entry box Android devices go back to showing the
telephone-style keypad instead of the alphanumeric one.
A new touch gesture on the waterfall for smooth frequency tuning: Touch two-fingers
horizontally, with a slight space between them, and swipe left/right to tune. Currently
you have to single-finger swipe on the frequency scale to smoothly tune. But this is
awkward because your finger always obscures the scale.
For reference, these are the other waterfall gestures currently supported:
Two-finger "pinch" in or out to zoom in or out centered on the passband.
Two-finger touch to pop up the right-click menu.
Single-finger touch to set the frequency, but with limited resolution unless zoomed in.
Pinch zooming on a trackpad now zooms centered on the passband (like it does on mobile).
Previously it centered on the low-resolution pinch position instead. This caused the
passband to frequently wander off the screen when zooming in. Zooming with a mouse
scroll wheel is still centered on the cursor position which is typically what you want.
Two-finger left/right swipe, as described above for mobile, does passband-centered
zoom in/out (the existing two-finger up/down does cursor-centered zoom).
Previously the behavior was undefined.
