Currently when setting any value you can type the unit (e.g. px, em, rem %) directly after the value and this correctly changes the unit for that property.
The exception to this is for unitless values (e.g. 0 or if specifying a unitless line-height for example).
Ideally this will work by type a single or double dash after the value.
Hopefully this is a straightforward addition and will aid in consistency and completeness, thank you for considering it.
