Hello,
I would like to swap the TX pin of UART1 to GPIO1? And Swap the UART0 to GPIO13 and 15.
I want to use Hardware serial for an NEXTION display and then use UART1 for Debug. If I could swap it as I mentioned I would be able to use the normal USB Connector of my wemos d1 mini for debugging.
With the actual library this is not possible, I think. I there any reason why it should not work if implemented in the lib?

You can swap, use hardwareserial on 13+15, and use softwareserial for debugging with the usb-uart converter.

or - to keep it easy - just use sw-serial for nextion
