Crossfades
  - crossfades automatically created when regions overlap
  - crossfades can be active/inactive by default
  - context menu control
  - no crossfade editor yet

Automation
  - all automation data is now drawn in its own track (1 track
      per plugin parameter, plus gain + pan)
  - direct drawing/editing of automation within these tracks now works
  - no selection possible yet
  - lots of refinement necessary

Routing
  - support for master and control outs
  - solo can be done using control outs, leaving master outs
     untouched, as required for live PA work
