We've decided to update XKit. It's harder than it looks. We're not in contact with the original XKit Guy, nor do we have access to xkit.info. We currently operate at this blog and on GitHub.
The greyed out font mentioned earlier is present in the bookmarks extension. Also I want to say thank you for taking the time to getting xkit more up to date!
This has been fixed and should be available tomorrow when the other person gets online.
