Does anyone else not like the idea of having dynamic signatures? Or in other words, prefer having the signature frozen with the post? To be honest, I'm surprised this change with signature handling was introduced in 6.0 and I'd be interesting to know why it was brought about.
Something else I'd prefer as well is having an option of whether or not to include one's signature when posting. This is useful when making News posts that also populate the main index of my site because I don't want my signature included with every News post. But with regular posts, I would want it included. For this to work, you'd have to go back to storing static signatures in the w3t_Posts table.
Finally, color markup doesn't seem to work with signatures as of v6.0.1.
Sorry for the part wish-list, part bug report post.
