It's bugging that the 'of' in the page x of y is still sans serif, but I don’t suppose there is a way to change that? I know I can have the format x/y but I don’t like that.
This is what is so great about the kobo though. The fact that we can tinker with these things.
ETA: I just realized the numbers are also sans serif. I’ll look around the patches to see if there is one to change this, and if there isn’t, I’ll be requesting this.
