Progress today (yet nothing to publish)
1st animation: how to add card navigation
► “Add complication” is updated to include cards and folders
► We can have only one card at the moment
► The top notification shows up right away
► I swipe down to hide peek card
(swiping down when card is hidden will reveal ambient screen as before)

2nd animation: how it works
► Youtube notification shown
► I start to play music on my phone, music notification appears
► Clicking the card expands the notification
► After hiding the card it stays hidden until a new notification comes in
(you can also see the notification count bubble change value/color in the background)

There is more work, expect a few more days before I can provide a beta version.
