In a future version of DMX Control, I would like to see a timeline-based cuelist editor.
This would provide a visual representation of all of the cues along a timeline. For each cue, the start time could be dragged to whatever time you want the cue to start (this would set the timecode trigger time). Similar to the way you adjust clip in and out times in video and audio editing software.
You could also have the ability to drag a handle to set the fade and delay times.
It would be particularly useful if you could overlay the waveform from a piece of music.
This would make creating light shows set to music much faster than the current method (getting the timecodes from audio editing software and manually typing them into the cuelist editor).
