Precise Text Size and Spacing Slider
A more snappy unit for text size and line spacing adjustment slider.
It is difficult to get a precise clean number with the current slider.
For example when I wanted to change a text size from 30 to 40 with the slider, it always ended up with numbers such ash 40.73 or 40.28
A more snappier slider that only move to round numbers or .5 increments would be easier to use.
