As a user of other audio video tools, I was looking for a really good, intuitive UI. I uploaded a 18Mb sized MP3 file easily. Next, I was able to add a text comment pretty easily at the time in the track I wanted. I moved down the timeline a few seconds, and right-clicked my mouse, expecting a right-button menu, but did not get one. i had to go back to the left side of the UI, and click on the ‘add comments’ command to insert my note. I had to do this a few times as I moved down the timeline. It would be nice to have a right-clickoption, rather than moving the mouse to the left side of the UI. Also, I found the UI not very intuitive. Overall, a great idea while collaborating on a music or video track. Look forward to seeing more fromthe team!
