Just change the size in the input element.

Let me repeat myself again: It's not meant to do all that. It's what it says: sentence case, which means capitalize the next word after a period and make the rest lowercase. It does what it was create for quite nicely.

If text width more than the width of the input, after you've enter new letter it returns you to the begining of the text, I think it's not convinient.
