The new "just press space to play and stop the timeline" is awesome, but it creates some questions about overall play/pause and stop workflow.
First I want to define the terms I'm using just to avoid confusion:
-play: play from the play-head (red line)
-pause (icon: two paralled vertical bars): pause the play-back of the timeline and place the play-head to that position
-stop (icon: rectangle): stop the playback and place the red line to the point where the playback started.
Currently pressing space plays and stops the timeline.
But instead I would prefer this solution:
Dynamic play button: when the timeline plays, the play button becomes a pause button (and vice versa).
Pressing Space plays and pauses instead of stopping.
The stop button still exists but uses another shortcut.
