thanks for the Update! I will look further into it before finishing the Review to your Plugin. Hopefully it will work even better now!
Also, I want to wish you a nice time at the Beach, hopefully the sun is shining at your site, in Europe the summer is rather rainy.
As an idea about the configuration tool:
The way you can configure the plugin right now is totally fine. As additional feature it would be great, if you give an expert option, so you can specify an url without doing the config-coding. Would be much handlier for experts (and lesse complicated). Any way, that's just an idea!
Edit: A masterpiece! I could not simulate any further error - all known errors are gone! Very good, the plugin runs even more stable than the old version. You really did a good job!
Edit2: Just wondering if it's possible to edit playlists on the Firefly-Server with this Plugin? Because if not that would be a nice feature, too.
