MySql latest tool, MySql Administrator has now been released. So if you signed up you should of had and email by now. Its only in alpha at the moment but from first impressions it looks to be a solid tool.
One nice feature that ive played with is the back-up tool, which writes an SQL script of selected databases and tables. Overall even though just in an alpha stage it feels like a solid more profesional tool compared to others released by MySQL in the past such as Control Centre.
