With all the Windows touch laptop / tablets coming out, it would be very useful to add touchscreen support to the software. Panning using touch already works. However pinch-to-zoom does not work. There are other gestures that could be added such as showing waveform info on single touch (rather than on mouse hover), etc.
I've tried the analyzer with a $100 Windows tablet and it works fine except for difficult navigation.
Considering how relatively easy it would be to add support, I think that this is overall a good idea.
