It would be cool if you would add my plugin "StreamingDrops" to the list of plugins that use your API.

StreamingDrops has its own placeholders for external plugins (no cloud download).

A link to the plugin:

An info about all available placeholders from PAPI:

If you need more information, please let me know.
