It's not the red dot I'm talking about, it's the fact that the game counts it as a wrong guess as soon as you fill in a word. I want to play around with the letters to make all three words before committing to a guess. But the game rejects every wrong thing you put in.

Gotcha. Your idea would be nice. It's not ideal, but in the meantime you can arrange the letters by dragging them around at the bottom.
