I liked your idea, so I made it possible to move the cursor horizontally by swiping a finger across the screen.
During the implementation, I encountered the problem of triggering on vertical scrolling, which leads to auto-scrolling to the entered text, which creates problems because it is impossible to swipe up or down perfectly. As a solution to the problem with horizontal scrolling, setting a flag is used to block auto-scrolling to the entered text. This solution puts a heavy load on CPU, and need to find a better way.
