I would like to see a "performance mode" setting where clicking anywhere on a clip (not just the tiny little clip launch button) would launch or stop the clip. "Performance mode" in this sense should be configurable to select clip on launch, select track on launch, or do not select on launch. This would make launching clips with a mouse or touchscreen much faster. A performance mode toggle should be on the main screen in session view.
I would settle for a way to resize the clip launch button to prevent fat fingering and require less precise mouse manipulation or encourage a touch screen in a live environment.
