I've used this bundle, but had some problems (it would skip certain files). On top of that, it just doesn't feel the same as the Cmd F UI in TM. I'd call the ack bundle a nice work-around, but I wonder why stuff like this isn't incorporated into the core of TM.

I've seen a few threads now about how an "Updated UI" would be a welcome improvement from the 1.x branch; I'd agree with that.
