KarenPrefs is a library that provides various conveniences and enhancements for developers seeking to create preference bundles for their iOS tweaks.
I originally wrote KarenPrefs back in 2013 for use with my tweak mikoto, but only thought about open-sourcing it recently, since I've found it rather useful (especially for when I need to show/hide specifiers according to iOS version, something I use often in mikoto).
