In amongst a chorus of "what took them so long", the Google folks working on the Chromium project -- the open source project behind the Chrome browser -- have at last added basic support for bookmark management in Mac OS X builds. Now, before you run over to the nightly builds page for Chromium, it's worth noting that the feature is still incomplete - you're not able to remove items from the bookmark manager -- you can only move them around. So there's still some way to go!

If you're using the Chrome for OS X releases, there's also going to be a little wait for the changes to move from Chromium to Chrome -- however if you feel adventurous, the Chromium snapshot builds will give you a taste of the feature (scroll to the bottom of the list for the most recent build).
