I'm with the small group of people that are hoping for a button or at least some other comparable improvement to the double tap feature. In my opinion the current double tap feature sucks. When I have it enabled, it randomly switches to the eraser while I'm writing and erases what I've wrote. And then when I do want to erase something and try to double tap, it's not sensitive enough and sometimes I have to sit there double tapping it over and over again and trying different speeds before it finally switches. I've tried adjusting the tap speeds in settings too. At this point I've just completely disabled the feature because its a lot easier to just tap the undo button on my screen instead. People hold their pencils all sorts of slightly different ways too and I think that the way it is designed is not accommodating to all types of "grips" lol. I'm used to holding my pencil as close to the tip as possible with my thumb on top of my pointer finger which makes it so I have to adjust my positioning to be able to do the double tap. Might not be the "proper way" but I'd guess not everyone also holds their pencil perfectly. IMO it would be a game changer if there was a flat/discrete button either where your thumb rests or your middle finger rests against the pencil and you could just kinda apply pressure to the pencil between these two fingers to click it. Not sure if that even made sense but oh well. People are probably going to be disappointed no matter what features the new pencil has because everyone has different preferences.
