UI of tasks inside collection on iOS

WHAT IS THE BUG

User interface on iOS for a collection of tasks.

HOW TO REPRODUCE IT

Create a collection with multiple tasks

THE EXPECTED BEHAVIOR

The individual tasks in the collection should have less vertical distance between each other, otherwise the user has to scroll unnecessarily. The checkboxes and their descriptions should not be contained in buttons. The “new” button on the top right should have equal vertical height to the filter button. The buttons of the filter menu should not have multiple shades of grey and a description which is clearly readable.
Additionally, when in dark mode the top of the collection page shows a grey outline when no cover is set - having this area fully black would look better.

SYSTEM INFORMATION

iPhone 11 with iOS 16.6.1

Is there a reason why you think that this is a bug report instead of a feature request?
