For a given input field, it would be cool to indicate the current cursor position and how much text is occupying it. It would be awesome if it’s easy to implement in any website without modifying the DOM at all. Here we got Smart Input Field Position Indicator jQuery Plugin.

It needs no images, it’s pure CSS rendering. It is accurate and dynamic, which means you can add or remove text and it will adapt. It uses Event-Delegation so don’t worry about performance if you have a million input fields or dynamically-created ones.
