I seem to be having an issue with the application where the tabs for World and Biome Settings are not showing up. I assume they're supposed to based on the cursory glance at your code, and that it's not because they haven't been implemented yet in 1.0.13. I can't get them to appear no matter the scale, and even reopening it doesn't help.
I'm on Windows 7, fairly old hardware, wouldn't be surprised if it's just me... screenshot attached.
