Does the spring-loading in Jaguar support column view? This would make so much sense, opening the highlighted folder to be able to drop the file into maybe a sub-folder of that one.
Yes it does. I saw a screenshot of it at ThinkSecret...
I did see a movie of it, too, somewhere, where if the window was partially off the screen, it would move to come on the screen so you could use the spring-loaded folders feature.
