In the v1.67 release I added some touch event support. So now if you zoom in sufficiently you should be able to touch-drag on the passband edges to change the bandwidth. You can also drag across the frequency scale to move the passband smoothly. tapping anywhere will set the frequency. Dragging outside the frequency scale (waterfall, spectrum, etc.) will shift the waterfall.
It doesn't work perfectly but it's a big improvement. Tested on iPad, iPhone, Android.
v1.60, to be released tomorrow, will fix a GPS bug that I finally understood today. Apparently, since v1.38 the GPS acquisition process has not been restarting after active users disconnect like it's supposed to. That will lead to the situation where the admin GPS page says "acq yes" (instead of "acq paused"), but there is no refresh icon shown in the "acq" column next to an incrementing PRN as is typically the case. The satellites that are already acquired and being tracked will be be fine until they drift out-of-range and are dropped. So eventually the GPS page will show nothing even though new satellites should be getting acquired.
I agree. It should work like a browser. I'll update the bug list. There was something similar on there before.
Also already on the list is the idea of having the classic A/B VFO buttons and a "band memory". So when you hop between bands using the select band menu it goes to the last selected frequency in the band instead of the mid-point, which is what it does now.
