Transmit 4 — Jaw on the floor! This is the future of Mac software. Absolutely awesome. UI beautiful. Animations beautiful and helpful. Performance fantastic. Absolutely love it. Apple should be taking notes (really, there's some nice UI paradigms that we haven't seen before on Mac OS X, or any platform for that matter). Check out the transitions in icon view! I love how they've written “that's the plan” in the description of the sync.
