Plugins / AB Repeat Toggle (Hotkey)
« on: August 31, 2024, 09:51:19 PM »
Download it from the add-on link here
NB: I'm yet to address one aspect of the plugin that'll currently prevent you from setting up the AB Repeat for the last played song from the previous MB session.
I initially planned to add this function to the other hotkey plugin I shared a couple of weeks ago, but I've decided otherwise.
Splitting them up will help with discoverability and ensure users get to download only the features they desire.
The function was requested here and I've been enjoying it myself too:
The entire code for anyone interested in taking a peak.

It would be great if AB repeat functionality could be added to Musicbee.
