Then to increase your odds of a successful suggestion, you might want to perhaps locate the proper place to post your suggestion. The category "Nextion / Feature Requests" that you have posted this to is more like requests that the Nextion firmware might one day include support for variable width fonts, or have increased usart throughput.

I am now reviewing all of the Feature Requests, this will take some time, patience please.
This is not Nextion Feature request - I will try to redirect
