I will be waiting for that new release, Steven.
I will share the source code of ths very simple plugin as soon as you have that new functionality.
I originaly built this plugin for launching a very light music player loaded with the track(s) selected on MusicBee. This light music player is configured to use another sound card, to wich I connected my headphones. This way, during live sessions, I can preview tracks from the MusciBee Library before I send them the MusicBee's NowPlaying List. On MusicBee's Preferences->HotKeys I configured a key for this plugin, so it's use becomes instantaneous. The applications and parameters it launches are configurable, so it's quite versatile. In the near future I would like it to allow to configure as many applications as you want, each one with a corresponding menuitem on the contextmenu and a corresponding hotkey.
Once again congratulations for the super good job, keep on. After 15 years using WinAmp I changed to MusicBee and became a big fan since its first versions.
