just noticied

[ghost]

passing zerorect does not work properly the layout is wrong, anyway good and solid job,

I created a set of experimental classes

NSUIWindowController (Nav Bar based and more)
NSUIWindow
NSUIApplicationDelegate
NSUIApplication

why ?call me crazy but it's just I tried it using cocotron,

I also added an experimental NSCoding capability to the view, xcode sucks about the XIB, they are totally convertible IB just ignore not found/ or "not understood" properties (except for the main one sure)

I also noticed that your tableView Object is really in a state of draft, maybe if people want to commit work, it would be nice to focus on this element as it's the base (I know implementation of the animations needed first)

Cheers!
