I highly recommend this application. The only feature I believe is a must have is the ability to align in the "TIMELINE" both video and audio. As it is you must view a lower left Video window and look up to see your audio time-line. This needs to be more like FCS where the Video and Audio are aligned across the time-line. A little more FCS seamless integration would also be beneficial - ie - your working in FCS - you desire to use SonicFire for an audio track - you simply "control-click" select SonicFire , and it opens (along with FCS) in a window.

Still highly recommended.
