One really cool feature is the shortcuts on some of the minimsed apps.
This deso not work for all but the media and email are two good examples.

On the media one you can pause the media or skip to the next track by small swipes within the minimised app.

Best explained on the Jolla help page:-

Works whne the minimised apps (covers) are big or small
It's all in the swipe!
