This is just a small improvement, but i found it helpful many times. Suppose you are in CSS and have a zero value (height: 0), now if i'm using shifter, the value increases, hovever the "value indicator" is missing (e.g. px). Of course it is not easy to know which string should be added to the number (px, em, rem, nothing at all?) - but at least for CSS files it would be absolutely sufficient to add "px" as a default if coming from zero (maybe even always if the indicator is missing).
