Drag-drop modes determines the behavior when one audio segment in timeline view is dragged and dropped over another.
These modes can be toggled from toolbar by simply clicking on the button or using the configured shortcut (default: D).
There are mainly three modes to choose from: Overwrite, Crossfade, Shuffle
This mode overwrites overlapping area from fixed audio with audio segment that is being dragged.
The fixed audio splits at the starting position of dropped audio segment and places it accordingly without loosing any data.
