Hey,
I've been looking for an alternative to Gerrit's code review interface and came across Mylyn, a plug-in for Eclipse with a connector for Gerrit. I'm happy to report that it does work well with our Gerrit setup. Now you can choose between two UX disasters :)
I'm not a fan of Eclipse, but it is fairly customizable, so if you have accessibility needs or would simply prefer to have a different layout for diffs, there's a chance you'll be able to beat out a better user experience out of Eclipse. Using Eclipse also makes it possible to do code reviews off-line and sync them later.

I started to document the configuration process over at [[mw:Git/Workflow]]:

I hope this is useful.
