Rated 4 out of 5 stars
I've been using this since before it was released, and I think the idea is brilliant - hence the stars.
I have one major issue that keeps me from using it. When using 'back', I often end up on some other page in the history. It basically makes it impossible to use - and therefore also hard to get on to more constructive feedback. I've reported this before - am I alone in seeing this?
