[FEATURE REQUEST] The lack of async on the controller makes it completely useless.

[sidetraxaudio]

Is your feature request related to a problem? Please describe.
Great work overall and I'd hate to be discouraging but external control using the controller is completely useless due to a lack of futures.
If you can't await for a task that is asynchronous by nature (aka anything on the internet) you can't write control logic. I'm very surprised considering how much good work you've done on this. I wondered if there is there an issue with decoding youtube responses?

For example:
Having a controller that contains the youtube controller and also stores the last playback position. When the user navigates back to the page that contains the video I want to 're-cue' the video at the previous position, pause it and wait for them to press play if they'd like to continue. This is not possible due to a lack of async programming on the controller.
It is impossible to:
seekTo(last position);
pause();
What is really needed is:
seekTo(position).then(pause());
or
await seekTo(position);
await pause();

Describe the solution you'd like
Implement async programming on the controller if possible because even basic external control logic is impossible.
