我是一个刚刚接触qgc的小白，现在使用的版本的3.5.4，我现在遇到的第一个问题是在用户界面有许多官网上提供的参数都找不到，找了相关的资料说是有隐藏参数设置，但是应该如何让他显示出所有的参数？第二个问题是在用户界面怎么更新地图？希望能够得大家到帮助，为我提供具体的步骤，十分感谢！

I am a little white who has just contacted qgc. Now I am using version 3.5.4. The first problem I have encountered is that there are many parameters provided on the official website in the user interface. I can’t find the relevant information. There are hidden parameter settings, but how should I show them all the parameters? The second question is how to update the map in the user interface? I hope that everyone can get help and provide me with specific steps, thank you very much!
It sounds like you are using ArduPilot and not PX4, right?
I suggest that you ask in https://discuss.ardupilot.org/.
用的就是px4呢，同时非常感谢你的建议！
