I'm not exactly sure what you're asking for, but ElasticWolf has a very nice and functional UI:
I've always thought the the web UI was meant for trivial things. For everything else, there's always the Command Line Interface.
On my opinion, they are the best in cloud hosting and yes they have complex but great UI
The console UI is not a perfect solution, but just works.
btw, I found an alternative UI designed for making automated job from Japan.
