I did some "hallway usability tests" in our hospital:
Most doctors find it more obvious to select stuff via the checkbox instead ctrl-clicking it.
(But they also say the new UI looks much cooler / modern :-)
Another issue on Mac: ctrl-click is by default mapped to a right-click.
That means every time I select an item the browser's context menu gets also displayed.
Could you add an explicit check-box as another method for selection, maybe as first item in an row?
I think this would improve the UX alot.
What do you (developers / users) think about this?
