It is a good day to… continue development of my pet project. Today, I decided to wrap the only `NSViewController` in an `NSSplitView`. IB overwhelmed me with a lot of objects, so I ditched IB in favor of programmatic UI creation. It turns out, it's not easy! The first search set the right mood (see attached image).

With this in mind, tools like SwiftUI and MacCatalyst make a lot of sense since they hide this complexity.
