Ya waiting patiently here too.
I think it is a bit more complicated than it seems. In order to pull this off they have to allow theming of some items that historically haven't been done. Like fonts in the Midi Window etc. Or maybe they just have to scale them automatically. I'm guessing that they didn't allow them to scaled via the theme before due to technical complexity as many have asked for that ability.
Not an expert or anything, but that may be part of it.
