I've just tried out using 'draggable.directionLock' for the first time and to be honest, it was a bit of a letdown, or let me put it another way: It doesn't behave like I've expected it to:
* For some reason, the draggable layer doesn't move within it's threshold boundaries, which is kinda weird. Does anyone actually want/need that behavior?
* Once you've dragged the layer outside of the threshold, the direction stays locked, even if you're dragging it back into the threshold-zone. While this may be useful in some cases, I'd assume 95% of the time you'd lock the direction manually via 'draggable.*direction* = false'. Especially since a ...
* Change of direction is only possible if you let go and re-click/tap the draggable layer.

(I know, my straight dragging is a bit unfortunate - but believe me, once it lefts the 'zone' it is actually direction-locked :) )
What do you guys think?
