The idea is to have a "LIVE" window for using studio one to control multiple parameters during a live stage show.
The LIVE window would allow you to drag and drop songs into a setlist, re-order those songs easily for quick set changes, and would load all MIDI / Automation for controlling external instruments and things like programmed lighting cues.
It seems like a simple feature to design, but being able to load individual songs into a setlist and reorder them on the fly would save a TON of time when it comes to creating my band's live sets.
