Container for apps to organize data

So i know they are available for pages, but i am wondering with all these posts about “migrating” to a new structure that Pages is on, will we be getting some of the features from Pages? As the title says, i’m specifically hoping for a container option.

There is just too much padding on many elements that it doesn’t look like they are part of the same “grouping” of elements. Then i end up adding more padding between sections, which is visually off-putting as well as it adds more work because i need to add visibility to these padding elements.
