@Eism I made a comment on Slack about the behaviour when a user double-clicks on a clip. We can discuss in the morning.

I'll repeat here:

For regular wave selections, it works as I'd expect.

• When I make a wave selection and press play, it plays through the selection and then stops. Great!

However, there's one issue: when a user double-clicks on a clip, in AU3, that made a waveform selection, whereas in AU4, it makes a new type of clip selection. Hence, pressing 'Play' will do something different in AU3 and AU4 when you've double-clicked on a waveform.

1. In AU4, when a user normally selects a full clip by clicking on its header - or if the user selects a group of clips, playback should not be affected by that. It shouldn't play at the start of the clip and stop at the end. So we'd need a special rule just for double-clicking on a waveform in AU4.

2. One option is: if you double-click on waveform in AU4 (which selects the full clip), then in that specific circumstance, when the user presses Play, it should play from the start of the clip until the end, then stop.

3. However, if point 2 is highly awkward, then we might consider going back to the idea that when you double-click on a waveform, it simply extends the wave selection to the ends of the clip, just like AU3 (see below), and we ditch the idea of double-clicking to select the full clip.

I'm curious whether either of these routes is difficult. I'm not sure which option I'd choose.
@LWinterberg any thoughts?
