Would love the ability, especially on web to allow the font picker to let me add any font name that I choose to the Typeface field for Text Layers.
The ability to hit cmd + enter from the search field could work well as a way to force the Name to be assigned. Also, keeping it dimmed, similar to the missing state show in the photo would make sense since it's not known.
There are instances where, on web, we might have to use a package such as Font Files to load in custom fonts but the UI restricts our ability to select them in that panel because it only offers the typefaces it knows about, which is somewhat limited, such as not knowing about local fonts, or fonts on a CDN.
