 ### New features & enhancements
 
-1. Minimum area size.
-2. More tolerating "safer" error handling.
+1. Areas are protected by a minimum size (not configurable for now).
+2. More tolerating "safer" error handling. If the screen cannot fit the minimum size of the layout, areas out of the screen will be hidden, but it will not crash the layout logic.
 3. Dynamic size adjustment with propagation.
-4. Editing non-global areas.
+4. Editor can be used on areas instead of entire screens.
