Bug / feature request - window size & column width

MacOS version:

i) window size
The Audirvana window cannot be made any smaller than nearly full screen – on a MacBook 12" screen.

It would be really helpful to be able to make the window any size I want. I would like to be able to make it roughly two-thirds or half the width of the screen, so that i can have this window unhidden (and thus displayed in Mac expose) – and still have it be entirely covered when beneath another track.

This is a common and standard feature in iTunes and most every application i have ever used.

ii) column size
likewise, the columns for “track number” (spelled 'TRAC", not sure if that is correct) “Title”, “Album” and “Artist” could be adjusted and made smaller.
