A wide range of mockups have been demonstrated for a new version of the 'View' screen.
Currently some new users find this screen confusing, whilst regular users can find it fast and flexible. The redesigns being discussed attempt to make it more intuitive for new users, whilst not removing power or speed. If you would like to contribute to the design, or are just interested in finding out about how new interface designs are developed, see this forum thread. Note that there are around 150 posts in that thread now over multiple pages, so it may take a while to absorb all the information!
