@Michal_Jurewicz: Have you found a developer?
Since Mike_Plugge has stopped developing the Roon Web Controller 2.0.0 Alpha (Roon Web Controller 2.0.0 ALPHA now available - #63 by Mike_Plugge), it would be great if someone else would continue the project.
I think the Roon Web Controller software is awesome and I use it daily. I would also pay something for the software if it was fully developed. The only thing I miss is the saving of the settings.
