Issues with UI in Pages

Hi Gliders!
Does somebody solved these issues with UI in Pages?

a) too big :anguished: spaces between elements\widgets on a custom screen like there TooBigSpaces.jpg - Google Drive

b) Losting top of screen in a Title Image :worried: within a couple of last weeks like there Filling top.jpg - Google Drive. Looks like developers changed rules for the top of layout?

c) Is there some way to put the CLICKABLE Iimage with wide filling all screen without borders. There were a few ways in Classic, but i found only one widhet close to this in Pages - the Title. But the Image is not clicable there :pleading_face:

Elsewhere the only way is to return to Classic)
Thank you :pray:
