Just because someone wanted it and I didn't find this function for tracks and streams, I created today a very basic plugin that jumps to the next track in the playlist after configured seconds.
So nothing optimized, first try.
No planning to extend it, take as is and use at your own risk, or fork it and improve it.
Nothing special.
UsageCopy dll to:
\PluginsEnable/Disable Plugin in Options and configure the time in seconds.
Config file is saved as:
AppData\PluginSettingsNextAfterTime.cfgand contains only the time in seconds in the first line.
