I have now had a look of this and I really like it!!
One small intriguing thing I have noticed:
When there is a function running, you can adjust the slider by dragging the slider button with the mouse. The value of the channel changes (remains changed) and the red X becomes enabled and works as exected. But, you cannot use the mouse scroll button for this. For some reason, if you hover over the slider, and move the mouse scroller, then the value changes while you are scrolling, but it snaps back to the scene's value when you stop scrolling. It is as if the scroll button does not trigger the new code. If you first move the button with the mouse, then the scroll wheel works.
One of my main use cases for this, is to make small adjustments to moving head spotlight positions during a show, when the actor singer has not ended up where we programmed her/him to be. Being able to make small adjustments with the mouse would be perfect.
