You're missing Fun Fun Pharmacy, a 1998 children's anime for which Konaka personally wrote every single episode's script. It was also directed by Yukio Kaizawa, who later went on to direct Digimon Tamers. And the character designs were done by Ikuko Ito, who did the designs for Magic User's Club and Princess Tutu (the latter for which he wrote several episodes).
Personally, I think both Tamers and Pharmacy are some of his best work. I would love to see him team up with Kaizawa for a children's anime again.
Here's a more complete list of stuff he's worked on:http://www.animenewsnetwork.com/encyclopedia/people.php?id=3612
It's actually still an incomplete list however, you'll have to go searching in Japanese for an actually complete one.
