I wouldn’t worry about the Server List at all if you know which two apps you’re going to be receiving from. It’s really intended for more complex cases where you want the selection to be made within QC.
If you delete it, you can manually put the names of the applications you’ll be receiving from in the App Name input for the Syphon Client patches, then name the files so you know which is which.
The Server List updates as servers come and go. The index is simply a position in the list of currently available servers. That patch is in a folder called “Examples”, not “Useful” 😉
