Interesting.
Regarding the smaller touch targets - what if the targets are not the whole tab blocks, but just the text area? “Home”, for example.
Also, previous commenter reminded me of how I had trouble with Microsoft Surface (6 or 7) tablet with touch screen l - when I held it by the bezel it turned out it already registered a touch input at the very edge of the screen, so when I tried to tap on the screen, it many times registered “two points touch” input instead and was really annoying. I finally discovered what’s going on with this issue when I was using Paintbrush and I saw the wrong strokes
Maybe it is similar on Scribe now that the bezels are a little thinner.
