Very useful, easy to use.
Very simple to use. The only thing that could be better in my opinion is the layout and interface. I feel that the frame selection bar would be better place at the bottom of the screen instead of the top. When choosing for a video, I was able to “expand” the video and it allows me to scroll to a frame of the video more precisely (if that makes sense?) but was unable to do so during the frame selection. It would be great if the feature could be implemented in the frame selection process.
