| Requesting a new feature
| -------------------------------------------------------------------------------------------------

Hi, 
I'd like to know if there's a list of available text features for a style guide.
I see there's:

```
    color
    fontSize,
    fontFamily
    fontWeight
    lineHeight
    marginBottom

```
but I'd like to know if there's
```
letterspacing or tracking,
uppercase
```

thanks
