I would like to see a new feature on WordPress. I would like to see the default comment system overhauled. The major change that I would like to see is the ability to have openID logins available to users by default and integrated into wordpress. I want so see logins such as Twitter, FaceBook, Google, etc. I feel that I should not have to rely on some commenting plugin that is not guaranteed to work properly with WordPress. I often find myself troubleshooting those commenting plugins and their features when getting them to work with my site. The most common problem I see is a problem getting the pingback/trackback part working properly with the blog, as well as integrating site login with it.
I would be happy to pay WordPress a small premium for them do develop this into a later release. The commenting system currently on the site by JS-Kit is not without issues.
