Description

// Create a window where you can have notes
// This doesnt preserve the notes between sessions. 
//
// check EditorPrefs Get/SetString to save the notes.

    var note : String = "Notes:\n->";
    
    @MenuItem("Examples/Notes")
    static function Init() {
        var window = GetWindow(EditorGUITextArea);
        window.Show();
    }
    
    function OnGUI() {
        note = EditorGUI.TextArea(Rect(3,3,position.width - 6, position.height - 35), note);
        if(GUI.Button(Rect(0, position.height - 30, position.width, 25), "Close"))
            this.Close();
    }    
}
