I understand, and that's why I'm a bit annoyed, it's a very developer-centric attitude propagated by the sentence above.

Personally, an end-user has never asked me to make their software/web-admin look unique. A portfolio site? Sure, but an admin page? Not other than their official color/logo in the header.

Uniqueness is just not a concern with "normal" people, and with good reason as I mentioned above. Still, congrats on the nice work on the site/post.
