Currently on Android, to drag and drop an item, you have to select and hold the bullet to the left of the screen. I assume it works the same works for iPhone.
However when this is done with your right hand, the step is inconvenient and probably used less for these reasons…
- The reach is far for devices with big screens or people with small hands
- Your hand blocks the line selected; the wrong line could be selected
- I know it is possible to slide your finger to the right while moving the task but this just adds to the finger travel required to re-position the task
An option to drag and drop from the right of the screen will improve the feature and make is more useful.
Having the option to select and hold any part of the line would be even better.
