The description for "Game Mode" flows outside of its alignment and the commands description for "Allow Cheats" flows into the Bonus Chest area. This isnt new, but with the new menu layout the element labels now flow into the other options, making the menu a bit confusing. Additionally, the buttons have non-intuitive positioning, so the menu misses a sense of heirarchy: the "Done" button on the More World Options screen is not in a central position and the options on the main screen are evenly spaced making the Create and Cancel buttons less obvious (something more like the first 4 on the more world options creen would be better.
The overflow issue with the gamemode can be fixed by moving the word the last word of the first line to start of the next line (it looks so much better; you will be immensely satisfied if you add the following to the lang file):
"selectWorld.gameMode.survival.line1": "Search for resources, craft,","selectWorld.gameMode.survival.line2": "gain levels, health and hunger","selectWorld.gameMode.hardcore.line1": "Same as Survival Mode, locked at","selectWorld.gameMode.hardcore.line2": "hardest difficulty, and one life only","selectWorld.gameMode.creative.line1": "Unlimited resources, free flying","selectWorld.gameMode.creative.line2": "and destroy blocks instantly",And the overflow for Allow Cheats can be fixed by using shorter commands ;
"selectWorld.allowCommands.info": "Commands like /give, /tp",
