1. Still need audio bussing. One reason for preferring Premiere Pro at this moment.
2. LFE Only option in Console ('audioextras') should be part of main program. It also has a bug in v8.5 where it applies to track to left of that selected & can be applied to stereo tracks, removing surround panner.
3. Presets for surround panner please (Center only, Front L/R no centre, Rear L/R no centre, LFE only etc etc) - available as right click within surround panner.
