They have released a beta version of WordPress 2.3.
I was testing it on my local install and it definitely looks much more promising. Inclusion of “Tags” feature to the core system is one of the major improvements.
At the same time, MistyLook 3.4 needed some tweaks for it to work properly in WP 2.3 and so I am in the process of making MistyLook 3.5.
If you are interested in trying it out, just leave a comment here, and I will send you the version by email.
