Make me replace Roon

I am a Roon user and just downloaded Corrd. Loving it so far. I need it to index my library and use those songs along with the streaming services. If it can do that I can stop giving Roon my money…I would also like to be able to provide a 3-5 song playlist and have Corrd create a multi track list for me to use. Perhaps it does this already. I am still looking for documentation and videos for support and information.
