Lots of people are raging about lost functionality, hidden UI elements, etc., on their forums.

I just don't like the way they've changed their use of color, spacing, etc. I don't like the options they've given us thus far. Moving text into the "compact" mode is a little better, but it's still pretty bad.

The classic interface is very, very well done. I don't use the calendar or filtering or rank things by importance - I feel for the people who depend on that functionality.

I have a gmail account that I use for mailing lists. The UI changes are not a huge deal for me, really, but it's annoying.

We'll see how it goes.

Cheers,
Scott.
