I would REALLY love to use the auto-generated FX Channel feature when dragging a plug out of a chain for that intent, but every time I do, I end up regretting it when I later realize I need to send THAT FX to another FX (like verb or something), and can't without recreating a new standard Aux Bus, copying over the FX chain, re-routing the i's and o's, and then copying over any automation written, and then hope like heck it all still sounds the same. Seems kind of silly to restrict an FX channel from sending to another FX channel.
