Good point about the font previews, but styling a select is much easier than it used to be. See here: https://www.filamentgroup.com/lab/select-css.html

Uninstalling and re-installing the package seemed to work for me.

You could always try throttling or debouncing the keyup event and then run the formate function.

I would personally like an option for 2 spaces. Maybe make this a setting?
