Hi Juan,
First, let me congratulate you on the work you are doing on PixInsight. This is a fabulous software. My personal learning curve was not to bad and farelly quick, thanks to the tutorials, and I am starting to be quite experienced with the software. I started to provide official trainings of PixInsight in Quebec, Canada.
It is nice to try to implement gesture more. However, a gesture should never be to select with a tap, at least not in Mac OS X. There are Physical clics for that on a Apple trackpad.
I personally never tab to click, and this feature is deactivated (it is by default). But I sure use the gestures (3 finger slide up, down, side, pinch motions, etc). If you force "tap to click" in OS X, you run into all sort of problems.
And I strongly disagree when you say:
"My recommendation is: always use an external mouse with PixInsight. Touch devices are very nice and fancy, but they are essentially useless for serious work.". I am a professional automation specialist. I have a degree in Medical Biology, another in computer sciences, and 15+ years of experience programming multi-million dollars system. And I seriously work with ONLY a trackpad, with a physical click on my MacBook pro. So please, do not mistake opinion and recommendation. I understand you said this to in honesty but a programmer should not ask people to downgrade when they are using the technology to full and as intended. I am using exclusively trackpads since 3 years, not because I am snob or don't know how to use a mouse, simply because they are an easier, compacter, more ergonomic and more productive way to control the cursor and multiple screen functions (pan, click, select, zoom, scroll, side motion, change screens, access, etc.).
This being said, I was using the click and move to Readout my images. However, since PI 1.8 RC4, I run into the tap to pan bug and I cannot readout. If you want a good gesture to pan, it would just be simpler to use the usual gesture which is move with two fingers. The zoom (currently the two fingers up) should be the pinch-in and pinch-out. A click should never be a tap. It should be a click. Please do not try to reinvent the wheels. Just use the already developed gesture and do not impose the Tap when people do not like them. Even on a PC, the tap to select is not a good thing and people tend to deactivate it, using their physical clicks. We should at least have the choice not to use the tap to select.
In the case of pan, a tap-n-hold with TWO fingers should be use to pan around. And a pinch should be use to zoom.
This being said, is there a way currently to avoid the Readout-pan behaviour?
Thanks,
Yanick
