Did some extra tweaks to 1440 height with "High Res Auto UI Scale" feature enabled.
Under this configurations now, the loading screen will show only 2 headers and group the unique items accordingly. Unique items are displayed in 2 columns which gives the "Begin Game" button some space.
As I tested other resolutions will just ignore this "High Res Auto UI Scale" feature so there is no need to create separate loading screen layout.
Again, thank you all for your support and feedback! Hope my creation made your gaming experience more enjoyable.
