Blank Spaces DO NOT CONVERT!
Come on! This is so half baked!
No field previews in page layout editor
It is NOT a technical limitation. LWCs can show field previews.
It is so hard to work with having that taken away, especially on very large pages.
Supported on custom lightning page layouts
Hiding of section headers
So no ability to do the standard two column to one column transition with no header visible
Narrow section Fields don't honour existing CSS
OMG They STILL have not fixed that the narrow column does not show in Compact Mode! OMG!
you STILL Can’t have two columns in the Narrow Column like you can with Related Record Components? STILL? FIX THIS!
Can't delete one column of a section
Can't delete multiple fields at a time
Can't filter fields by types, like you can for reports
No read only indicator
No required indicator
No indication that the field is a formula field
No ability to add custom report links to the bottom of the page
No direct link to the object from anywhere on this builder page
Now that the Detail page is gone.
Issues
It is still so very slow to Save the page - about two to three seconds slower. And that is really noticeable.
