So I took the general design and added a ton of features, allowing for a completely white label WordPress admin.
I ended up launching Slate Pro exclusively on Envato’s CodeCanyon site. I’m not especially happy with the initial pricing of $14 they set, but it’s hard to pass up the sheer volume they can theoretically provide. And they have a 100% GPL licensing option available, so I still feel good about being part of the WordPress community at large.
