I've implemented a KiCad footprint that provides an "oh fuck I got tx/rx backwards again" crossover box. Not my idea but I forget where I first saw it (I think it was here on Fedi). Fit two resistors (or solder bridges) horizontally and it's straight through; fit them vertically and it's a cross-over.

ETA: the name of the footprint is “Oh_Fuck”.

A kicad footprint that is two resistor footprints, where the resistors can be fitted vertically to swap two lines, or horizontally for straight through
3D render of the crossover footprint, showing that it conceals the fact that you are a doofus who often gets data lines bass-ackwards.
