Use space bar for pause and play
Use cases
Desired behavior
When user hits the space back, it would pause the currently playing track. Pressing space again would continue playback from where it was paused.
Benefits of the solution
This is common functionality across most music or podcast players. It would create a familiar and easy to use experience for users right out the box. Also, many hardware does not feature media controls on thhe keyboard, so the only current way to pause playback is to navigate to the application.
Possible drawbacks
I am not sure of any drawbacks this could present, unless it would interfere with any current functionality or create bugs.
