Hi,
I totally appreciate that in regards to the drop target - having been a SW developer - but the missing icon on dropping a url from a browser (which would create a shortcut when dropped in the desktop) onto a dock, I would consider a bug. I agree that picking up the favicon of the site would be a new feature - that was just an idea I had when I wrote my last message.
(by the way, I just tried to drop that URL on the desktop - which created the expected shortcut - and then dropping that shortcut onto my tabbed dock, also created a link without an icon, while a shortcut to a pdf created the link with the correct acrobat icon.)
Cheers,
Gunter
