-1.参数编辑时候崩溃bug。参数编辑窗口，添加，点击参数名称，在蓝色状态时候点击字母按键会崩溃。后续进行过某些操作就不会崩溃了。
-  解决方案
-	a、修改当前的crash（解决）
-2.参数编辑，第一次生成matlabparam还是在workspace下，后续生成在release下，simmatlab文件需要保存在release下才能运行。参数文件和运行的.m文件路径需要统一
-  解决方案
-	a、放到想定空间所在的目录
- 
-3.窗口1的Report和窗口2的Report Table 展示的是不是同样的内容，如果是可以删除一个。需要在窗口1或2看的report时候通过窗口管理拖动实现。
-   解决方案
-	a、保留窗口2的Report Table （解决）
-	b、窗口2中的Report Table, 可以拖动变成dock模式添加到其他的窗口中
-	c、有缩放属性的控件，鼠标都显示为双箭头 （解决）
-	d、所有的窗口表头可以采用拖动的形式调整列的位置 （解决）
-	
-4.需要连续用到的操作、功能类似的放到一个大界面。这些不知道具体怎么分就需要讨论细分一下比如：
-功能控制一样的：窗口管理和ui设置都是控制界面的放到同一个栏目
-   解决方案
-	a、窗口管理放到系统管理里面，点击按钮，弹出菜单可以勾选 （解决）
-	
-操作步骤连续的：①参数编辑②MatlabParam文件关联③SimMatlab关联④运行.m文件。这些放到一块方便操作
-    解决方案
-     a、暂时不动
-	 
-5.关联文件时候更改文件的按键不太明显。
-	解决方案
-	a、属性控件文件选择按钮不明显 （解决）
-	b、属性控件中间的分割线能左右移动 （解决）
-	 
-6.提供的轨迹文件是如何输入到dyt界面的，我们需要知道。
-    解决方案
-	a、下次发版带一个配置好的空间想定
-	  
-7.属性、实体、report等这些窗口，加上稍微明显一点的边界，然后点击边界拖动时候改变窗口大小或者改变位置。就和桌面上的文件一样任意改变窗口大小和位置。
-   解决方案
-    a、界面美化，层次感 (解决)
-	b、鼠标拖动放大缩小之后，松开鼠标再次拖动无法缩小 （解决）
-	c、所有窗口都用dock形式，用户随意拖动放置到其他窗口中
-	d、窗口布局影响窗口位置
-	e、窗口会自动变大
-	f、report窗口能分离出来 （解决）
