Thank you for the contribution and your involvement. It's a good start! I tested it and I think it'd be better if the loading bar (blue animated top stripe shown on refresh) would not receive the padding. See the screenshot.

So applying the window insets padding to

• LazyColumn in CalendarListContent in SubscriptionsScreen
• HorizontalPager in EnterUrlComposable (instead of AddSubscriptionScreen)
• Column in SubscriptionSettingsComposable (instead of AddSubscriptionScreen)

would look better, since the loading bar will be able to stretch the whole screen width (up to the 3-button navigation) again.

Additionally it would be cool if you could also add the window insets padding to the FloatingActionButton in SubscriptionsScreen as that one seems to go below the 3-button navigation in landscape mode.

Again, thanks for the help. We appreciate it!
