Adding new tracks in Track View idea.
I think there are very specific track types that can be added as "new tracks"
1) items from MTP 2)Audio-blank 3)MIDI-blank 4)Chord Track

Suggestion/idea:
A "plus" icon on the top right. When pressed an intermittent small popup appears (disappears when choice is made) with 4 choices:

Library - opens MTP at RT tab by default. Users are free to roam audition and choose whatever they like from MTP and the track will adjust accordingly. Function wise pretty much to what we have now.

Audio - Will open a blank tracks with "Arm" for basic audio recording.

MIDI - Will open a blank MIDI track

Chord Track - Will generate MIDI chord track. This one is a little tricky as there are two kinds of Chord Tracks with different functions, so I will revisit the suggestion when idea puzzle comes together.
