so it's actually a pair of ` and' to include the whole ifelse sentence is needed, no matter how much lines it occupies?

@Keyon I guess so, I noticed that the string "mux/demux" setting below works, but this part didn't. I was debugging this for 3 days, since the string shows it is "MUX", but I never looked at the uuid. In the fw mux/demux share almost all function pointers, only copy function is different -> when copy crashed, the log was missing the last bits -> I didn't understand I was actually running demux instead of mux...
