>>> Yep, the Windows client already works that way. It shouldn't be too much trouble to get the Mac client up to speed. <<<
Rusty,
It's in 5.7b8 and it's fast and it's wonderful! And more beautiful than I had expected, because 'By List' and 'By Icons' are also clickable in the window. This is even better than what the Finder offers!
One more wish in this respect (as you know): Remembering window positions and size on the user's screen, independent of the positions on the host.
I appreciate it may take some work, but I'm sure it wil be greeted with great enthusiasm!
