We've started to adopt workboards, and I, for one, am finding them pretty useful. There's one friction point that I run into a lot, though: usually, the full name of a task doesn't fit on the card, and I have to open the task in another window just to see the full name. I hovered my mouse pointer over a title expecting a tooltip, but none popped up. A simple tooltip with the full task name would work, although the nifty tooltips that show if I make a task reference (e.g. T1234) would be really awesome.
