Hey, and thanks for the great game!
I usually play on mobile in portrait and I find that the automatic scrolling sometimes gets in the way. Here is a concrete example:
Here I'm looking at the words on the right but noticed the lone T, so I want to click on the red square to just drop the T. But clicking on it unexpectedly scrolls to the left and then I misclick the T because it moved away.
Maybe the automatic scroll should only activate if we are filling a word from the beginning? (i.e. if all cells in the current word that are before the current cell are already filled) Or something similar.
