Nine days and nine minor characters I liked

With nine days to go before the opening of The Deathly Hallows, Part 2, I thought I'd think about some of my favourite minor characters from the novels, characters I would like to have seen given bigger parts in the books:

1. Cho Chang, Harry's love interest in The Order of the Phoenix. I thought she worked well with Harry and I thought her confused feelings after Cedric Diggory was murdered were really interesting;
2. Cedric Diggory, of course, because it was nice to see another truly good, heroic character who wasn't part of Harry's circle;
3. Nymphadora Tonks, who was a cool combination of fun, clumsy and heroic. She was an Auror, after all, and Mad-Eye's protege, so she must have been pretty good;
4. Neville's Grandmother, because the brief glimpses we have of her suggest she's a pretty neat grandma, and tough as nails as well;
5. Professor Sprout, who comes across as a solid citizen but never gets a chance to show off the full range of her character;
6. Penelope Clearwater, the person with one of the best names. If she can put up with Percy, she must be okay;
7. Molly Weasley, the matriarch, who finally gets to strut her magical stuff in the final book;
8. Minerva McGonagall, the tight-wound Assistant Headmaster, who from time to time is allowed to show there's a sparkle underneath all that control; and
9. Luna Lovegood. I mean, who can get enough of Luna Lovegood?
