Well in epiphany we have a way to map the URI to an action. Though doing
it in drag_motion can be more tricky than doing it on drop. (like you
dont want to keep an unused action around if the user cancel dnd...).

I agree that if the Mac OS X is the behavior we want, it's not worth to
bother.
I talked with seth about this. He think Mac OS X implementation is ok,
though without mac like phisical movement it could be confusing. IRC log
follow... case 1 is Mac OS X like behavior.

<seth> marco: I can see benefits of both, but if case 1 is substantially
easier to implement, I think it is OK

<seth> marco: The problem is that without physical animation like on
OS/X, case 1 could be confusing
<marco> seth: yeah I think 1 is much much easier to implement
<marco> seth: not sure what you mean with physical animation ... never
seen OS/X myself
<seth> marco: On OS/X things don't "jump"
<seth> marco: They slide
<seth> marco: They move around on the screen, not just jump from
location to location
<marco> seth: oh right I see now
<seth> marco: So in OS/X when you are dragging into a toolbar, other
icons slide out of the way, so its clear what is happening
<seth> marco: In GTK they'd probably just jump out of the way, which
could be confusing
