Some month ago I was looking for a newer version of DB designer. I don't found one since this project died. But it's source is used for MySQL workbench - but I could not find a release.

Then wildan-maulana mentioned MySQL workbench. I remembered that MySQL workbench is the follow-up project of DB designer, which I realy liked. I tryed the OS X version but it crashes when I create a new table :-( Maybe I have a look at the Linux i386 version in the next days.
