(I swear this used to be possible, maybe back in the Typekit days.)
I need to be able to see how large my embedded font kits are. As I add and subtract fonts & families to my kits and try to choose the right character sets, I need to be able to more easily balance browser performance with design flexibility, and I can't do that without being able to see how large my font kits are.
Also, I can't rename my kits. 😞
