Have an option where the cursor does not jump back to corrected word after an autocorrect.
When typing, autocorrect will activate after entering a space. The cursor then jumps back to the end of the corrected word, leaving a space hanging out after the cursor. Because the space is invisible, it is easy to forget and just make another space. This builds up a bunch of spaces to the right of the cursor. Just typing this so far, I have six spaces to the right of my cursor.
This also causes a problem when I am trying to type a certain word, and autocorrect is being overly aggressive, and repeatedly overwriting the same desired word.
