KTUIKit - Layout Managers for Cocoa

Cathy Shive has released a framework called KTUIKit that provides better view controllers, easy ways to set view background colors and borders, and a basic layout manager class. I think NSView’s spring and strut system is the weakest part of Cocoa. It works fine in simple cases, but when you have multiple panes in a window or you need to resize a window through a wide range of sizes, it falls apart. KTLayoutManager looks like a good start at solving this problem, although ultimately I think it should be addressed in Cocoa itself.
