Feedback from a Chinese user.

Hello, developer, I really like this software, so I have been supporting genuine. However, I encountered a problem in use and wanted to give feedback.
When I set the close function to three fingers and pinch together, and when I set the exit to three fingers, I often don't respond when I make these two gestures on the touchpad.
But if you set it to other gestures, such as setting the exit to four pointing to the left and setting the closing to four pointing to the right, it is very sensitive and easy to use.
I want to say that can you optimize the function of the three fingers?
