Is it possible to adjust letter spacing in spark?  i.e. like in CSS:

letter-spacing: -.52px;

Hi John,
I asked our internal team about this and at this point there is not a way to adjust but you do have these available properties:
Family
Size
Weight
Line Height

Thanks for continuing to dig into Spark and keep the questions coming!

Is this something that will be added?  

I appreciate the direction of limiting the CSS and class definitions in favor of smoother upgrades and versioning, particularly in regards to DOM structure updates which I know can be painful.  That said, it would go a long ways to be able to add specific styles.  Perhaps there’s a middle ground by adding the ability to add styles in the DSS to defined elements without overriding the class hierarchy.  This could be similar to how in the V1 API you could add styles to a wrapper component in the page builder.
