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.
Re: Greyed out Font. I took the liberty of checking to see which buttons were still down and it appears that Check Post Limit, Blogs Similar To and Blog Tracker are still greyed out, as well as all of the queue+ and draft+ options.
Now fixed for Draft+, Queue+, Check Post Limit, Blog Tracker, and Outbox.
