I'd like to see selecting instruments for Midi tracks simplified for 6.2, specifically I'd like to see the ability to select the plug-in I'd like to use selectable from a drop down list in the Graphic Editor window. I'd like to also select my bus from this same window (basically everything you need to set up VSTi's would be nice here). The Band and Pgm # already exist here, I think it would be much more intuitive to be able to work on all aspects of a track from this one location. Maybe a button to bring up the Effects/Synths window when necessary specific to the current track.
I hope it's relatively clear what I'm asking for. My biggest gripe with Metro is dealing will all the various windows. Eliminating the need to switch around would help a lot.
