As you said Compiler the need is not obvious, the trick is to have only one thumb to deal with. But I understand that in some case: have both a .rsr and a .png and don't really which of the 2 has the good picture it can be embarassing of having only one thumb. This will rather be a switch than an option on/off, so you'll able to quickly switch from a P3dO point of vue to an Explorer point of vue. I needed your opinion because it wasn't clear in my mind and also it's always better to ask before than after ;)
