The new D365 V9.0 user interface (Unified Interface) looks nice and its not as functional as it used to be in 2016 web interface.

New UI in web interface looks clean BUT it has too much space between fields.  For example, in Lead entity, spacing between fields like "Topic", "Name", "Job Title" fields are too wide.  Because of that, you can't fit many fields on the form before you have to scroll.  It would be nice if we can have the option to control the spacing between fields in the form or reduce the spacing.  On "Address" composite field, the fly out address fields get cut off from the screen when user click on the composite field and the user has to scroll to get to rest of the fields.  The fly out fields should be made visible entirely on the screen.

In addition, the Business Process Flow banner and entity record label (including header) is taking too much real estate in the form.  It's taking up 1/3 of the screen vertically that is static.  There's too much white spaces.  Again, if there's a setting that user/admin can set as "optimized" (less white space) or "clean" (spread out), that would be helpful.
