I agree about the hidden category. However, I don't think that was what Abella was questioning. Rather, it was the displaying of the icons - The KDE3 displays inline while the KDE4 forces a paragraph break, placing itself between.
My feeling is, that we need the hidden KDE3 category (and we probably don't need one for KDE4) but that the displying of the two should be the same, and in fact like the KDE3 one.
Yes, but by editing it to make it virtually the same template as KDE3 I should have fixed that as well :-D Didn't test it, though, so
