I would like to request the following features or know where to find them if they already exist.1. The ability to remove/delete/cut a portion of an audio file without the rest of the track changing position. Right now if you take a song and remove/cut a section of it the two portions join together and change the location of all the other clips on that track.2. The ability to add an empty track.3. The ability to drag a clip from one track to another.
