For me the major problem I noticed besides smaller usability problems is that if I use only keyboard - ie. F10 to get to the menu and then navigate to indicators - if I get into the calendar widget, it seems there is _no key at all_ that can be pressed so that I could close the indicator or get out of the calendar widget. That means alt-tab, F10, Esc, arrows, nothing helps. Which means that without a pointing device, or eg. a broken pointing device, person is actually completely stuck inside the widget until forcefully rebooting the computer (or switching to terminal and killing some processes).
At the very least handling Esc in the calendar widget to close the indicator before natty release should be done (if changing the widget to another gets delayed).
