Recommend: Adding spacebar cursor feature
Have you ever found it frustrating when trying to add or remove a letter from a word in a sentence you already typed, but your fat fingers can't put the cursor in the right spot to make the edit? Why not add an easier to use feature through the use of the spacebar?
Tap on or near the word you want to edit to bring up the cursor (of course its in the wrong spot because you have fat fingers)...then, hold down the spacebar and drag left or right until the cursor is in the right spot. Release spacebar and make your edit.
