Having Row field and Column sub-field would create the power of a real page builder, it could compete with any other.
- Individal Rows settings
- Individual column settings
- Control what blocks can go to Row
- Control what block can go to column
- Less code needed
- Endlessly more powerful
- Better user experience
Layout field is good progress, but it is very static and restrictive:
- No control over the columns
- If user wants to change layout he must create new layout and transfer all content there manualy. Or delete everything and start again
- Lost option for complex blocks. Very complex blocks can’t go to column.
