Wrapper for:

[tyy-dev]

 /// <returns>The view instance.</returns>
 public T OnSchemeChanging(Action<ValueChangingEventArgs<Scheme>> callback)
 {
     view.SchemeChanging += (_, e) => callback(e);
     return view;
 }

 /// <summary>
 ///     Subscribes to the <see cref="View.SchemeNameChanged" /> event.
 /// </summary>
 /// <param name="callback">The callback to invoke with the <see cref="ValueChangedEventArgs{T}" /> containing the old and new scheme names.</param>
 /// <returns>The view instance.</returns>
 public T OnSchemeNameChanged(Action<ValueChangedEventArgs<string>> callback)
 {
     view.SchemeNameChanged += (_, e) => callback(e);
     return view;
 }

So we can just define them as a Dictionary maybe? This is DRY Violating
