improve multimedia functionalities

[mathematicboy]

Hello.
Is there any plan to improve multimedia functionalities of buttons? I think it would be very interesting. For instance:
-Open a multimedia window (similar to any computer media player window) where you can pause, resume or play at a specified point in the timeline.
-Add a volume control in each multimedia button in order to play each multimedia button with a different sound level.
-Improve the loop function. For instance, an interval of the track is reproduced once, and after that, a different interval of the track is looped.
-Create "fade buttons" in order to fade out or fade in a particular media button which is being played, and even crossfade between two multimedia buttons.
