I often read my notes on mobile phone while on public transport using one hand with a lot of jerks. So the read mode automatically switches to edit mode and I end up adding characters unintentionally.
It will be nice to have this disable feature coupled with changing double-tap sensitivity. Like mentioned in post below.
I feel like a time-between-taps slider would be a good idea for accessibility, like the adjustable double-click interval on desktops.
