How about displaying the operations in a specific window?

Hello, can you add new features?
For example, the keyboard and mouse operations are displayed in a specific window, and are not displayed after switching to another window.
It is inconvenient to display the keyboard and mouse operation through the alt+b switch.
您好，可以加入新的功能么？
比如在特定窗口内显示键盘和鼠标操作，切换到别的窗口后不显示。
通过alt+b开关显示键盘鼠标操作，这样不方便
