We actually went part down the road of Uservoice integration and it was going to make the first cut but due to a few issue we had it's been put on hold. We'll get it in soon though, I promise.
Wanted to complement you on the design as well, looks really nice! Just one issue, the background is flickering on my Laptop's screen (Lenovo T510i). No of to explore your solution some more.
I find the text really hard to read when configuring a widget.
Also, uservoice support :)
