This would be handy when using MusicBee to play to an audience.
I get a bit stressed selecting tracks knowing that an accidental double-click will noticeably mess everything up.
This could be implemented with additional options in the
Now Playing settings.
Adding an option to
Do Nothing to each of these menus:

...would:
* allow disabling double-click entirely (as per OP request)
* play or queue selected tracks when playback is stopped (which most people would probably expect by default)
* prevent accidental double-clicks from messing up playback and queued tracks when something is already playing.
Bee excellent to each other...
