The only one i still have issues with is going from xbox to nintendo controllers, because they use the same abxy face buttons, but they switched them around.
I like what switch games do when you’re using a single joy-con, they just show a button with an arrow pointing to which direction the button is, so what’s printed on the button doesn’t matter at all.
I usually put them in /media, so my games drive for example lives in /media/games.
Seems to mostly fit with the usual external media that gets mounted there.
