ERIK.SWANSON  This looks very interesting. In the few minutes I've spent playing with it, I've managed to substantially clear out my overgrown "Downloads" folder by moving things closer to where they belong.

ERIK.SWANSON  The not-so-obvious advantage of the drawer over "normal tabs" is that you can scroll them—you're not limited to only having easy access to the first few tabs.

(After getting used to this, I've grown to hate browsers that force me to use a clunky pulldown menu to access "extra" tabs.)

ERIK.SWANSON  I too am experiencing system freezes whenever I try to launch SSHKeychaon 0.7.1 after installing Security Update 2006-003 on my MacBook Pro.
