Maybe I’m weird, but I quite enjoy starting from a blank song, throwing my racks in and wiring it all up!
Admittedly some aspects of it are tedious though. One thing I’d like is for racks to optionally have a default output route (or routes) that wire themselves up whenever you add the rack to the song. I suspect a very common situation is where you always wire your rack to the audio output (or certain racks to certain audio outputs etc). Particularly in Cantabile 3, when it always feels like the best thing to do is put any effects plugins inside racks, so you can drop a rack in for a particular sound in a very modular way, and so rack outputs are often likely to route to the same place.
